Introduction
1.1 Overview
MT1200A, MT1201A and MT1207A are voice trunking gateway units that enable digital T1/E1 or analog voice channels to be compressed and extended over an IP or serial link. These units implement G.723.1, G.729 A, G.711 compression and
TDMoIP or MPLS multiplexing algorithms to send up to 30/24 digital or four analog voice channels over an IP or n x 64 kbps network, with transparent CAS and CCS support.
MT1200A, MT1201A and MT1207A units utilize voice activity detection, silence suppression, echo cancellation and other techniques to improve voice quality. The gateways detects, generates and relays DTMF/MFR2/MFC signaling. In addition, they support fax relay and voice band data.
The units can be managed locally via an ASCII terminal or remotely via Telnet or
SNMP-based network management applications.
Versions
Note
The following voice trunking gateway unit models are available:
• MT1200A provides a single T1 port that can support up to 6 digital voice channels
• MT1201A provides FXS ports to support up to 4 analog voice channels
• MT1207A provides a single T1 port that can support up to 24 digital voice channels
• MT120 xAE provides a single E1 port that can support up to 30 digital voice channels.
All the above models are also available in DC-powered versions
In this manual, the generic term MT120xA is used when the information is applicable to all equipment versions. The complete equipment designation is used only for information applicable to specific equipment versions.

Chapter 1 Introduction
Features
Ethernet Links
MT120xA provides two half/full duplex, 10/100BaseT Ethernet ports, each with autonegotiation support. One port functions as the uplink to the IP network, while the other is provided for connecting the user Ethernet LAN to the MT120xA unit.
Together with the MT120xA's integral Ethernet switch, this allows integrating the user LAN traffic with the compressed voice, over a single uplink to the network.
If autonegotiation is disabled, the Ethernet ports can be configured to any of the following operation modes:
• 10BaseT – half or full duplex
• 100BaseT – half or full duplex.
The main link Ethernet port supports direct and indirect connection to the IP network.
Serial Main Link
MT120xA has a single TDM link with a RS-530 interface. This serial port supports n x 64 kbps data rates, from 64 to 2048 kbps.
In addition to the standard RS-530 interface, the following serial interfaces are supported by connecting an interface adapter cable to the MT120xA unit's RS-530 interface:
• X.21
• V.35
Voice Interface
MT1200A and MT1207 each have a single T1 digital voice interface, while
MT1201 has four FXS analog voice channels and MT12 xAE has a single E1 digital voice port. The voice interfaces control the T1 or E1 frames, use G.723.1
(6.4 kbps), G.723.1 (5.3 kbps), G.729 A (8 kbps) and G.711 compression algorithms, and handle CAS/CCS signaling transparently.
Voice Activity Detection mechanism allows optimizing bandwidth utilization, as
MT120xA generates traffic only when voice activity is detected. MT120xA uses the
G.723.1 A and G.729 B techniques for silence suppression and the G.168 standard for echo cancellation (up to 16 ms per channel). MT120xA detects, generates and relays DTMF/MFR2/MFC signals. In addition, MT120xA supports
Group III fax relay (4.8, 9.6, 14.4 kbps) and transmits voice-band modem data.
TDMoIP Multiplexing
MT120xA encapsulates the payload bytes in a UDP frame that is transferred over
IP and over Ethernet.
The number of TDM bytes in a multiplexed frame and packetizing interval are user-configurable.
A destination IP address can be configured for each bundle (see Bundling, below).
Overview 1-3
Chapter 1 Introduction
MPLS Multiplexing
When using non-IP based Ethernet networks or the Serial uplink, the MPLS format can be used instead of TDMoIP. The MPLS header is smaller than the TDMoIP header, saving about 5% in bandwidth.
Bundling
A bundle is a logical internal MT120xA port, containing up to 30 timeslots.
MT120xA supports 12 bundles. A bundle is routed to a defined remote IP address.
Each timeslot can be included in any bundle. At the remote site, it can be connected to any timeslot within a destination bundle.
Bundle QoS supports:
• Labeling IP level priority (ToS).
• VLAN tagging and priority labeling according to IEEE 802.1p&Q.
The user can configure the ToS (Type of Service) of the outgoing IP packets. This allows an en-route layer 3 router or switch that supports ToS to give higher priority to MT120xA traffic for delay-sensitive and secure applications.
MT120xA allows you to configure the whole ToS byte field, since different vendors may use different bits to tag packets for traffic prioritization. This also enables you to work according to various RFC definitions (for example RFC 2474, RFC 791).
Timing
Available timing modes for the T1/E1 voice ports are:
• Loopback – The transmit clock is derived from the TDM receive clock.
• Internal – MT120xA features an internal oscillator. When MT120xA is configured to operate with its internal clock, transmit (Tx) and receive (Rx) trunks use the clock supplied by its internal oscillator.
Available timing modes for the serial main link are:
• DTE – port accepts receive and transmit clock signals from the communication equipment, e.g., modem, connected to the main link. This operation requires an adaptor/cross-cable.
• DCE – MT120xA provides the transmit and receive clock signals, derived from its internal oscillator, to the communication equipment connected to the main link.
Diagnostics
MT120xA supports local (internal) and remote (external) loopback activation on the T1, E1, and FXS channels. The user can also perform tone injection towards the local PBX or analog equipment. In addition, a ping utility is included to confirm IP connectivity to the remote units.
1-4 Overview
Chapter 1 Introduction
Statistics Collection
MT120xA provides extensive statistics collection capabilities, which include
Ethernet (as per RFC 1643) and HDLC statistics, voice, signaling, bundles, and
CPU utilization.
Management
MT120xA can be managed via a local terminal, Telnet or SNMP network management systems. MT120xA has an RJ-45 port for the direct terminal connection. Alternatively, a supervisory terminal can be connected via a modem link.
Software upload and download and configuration can be performed via the local terminal or TFTP. Remote units are managed via Telnet or SNMP over an in-band management link.
MT120xA supports a four-level security and user-authentication system:
• Administrator – Allowed to configure all the MT120xA parameters.
• Operator – Allowed to perform all operations in the system except for user administration (adding/deleting users, changing user definitions).
• Technician – Allowed to test MT120xA and monitor its operation (for example, monitoring alarms).
• Monitor – Allowed to monitor the MT120xA operation.
When MT120xA is managed over Telnet, up to five simultaneous management sessions are allowed. Access to the MT120xA software can be limited to the ASCII terminal and SNMP management by disabling the Telnet access.

• MT1201: Four FXS analog ports that connect to POTS or faxes.
• MT12 xAE: One E1 port, which receives E1 trunks from PBXs
Signaling
Signaling information is processed according to signaling mode: CAS or CCS.
• CAS – The signaling data is processed by the unit’s host by extracting the
ABCD bits and reporting any change in their status to the host. The reporting format is similar to E1. In addition, the signaling DSP employs a refresh mechanism to update the host with the most recent status of the ABCD bits.
The ABCD bits can be manipulated by using translation rules, which are defined by means of signaling profiles.
A profile enables the user to select the translation of each individual signal bit.
The available selections are A, B, C, D (value copied from the corresponding incoming bit), NOT A, NOT B, NOT C, NOT D (inverted value of corresponding incoming bit), 0 (always 0), and 1 (always 1).
In addition to the translation of individual bits, the signaling profiles can also be used to define the signaling bit patterns that indicate the idle and OOS states.
Functional Description 1-7
Chapter 1 Introduction
Note
• CCS – The signaling information is transferred transparently to the host, which encapsulates the HDLC frame with the proper IP header and sends it to the main link. The following protocols are supported: ISDN, QSIG and SS7. HDLC data can be extracted from any set of timeslots and sent to a single destination.
When operating with SS7 signaling, it is possible to control the amount of keep-alive messages transferred over the signaling links.
Compression
The DSPs handle the voice traffic by compressing it according to G.723.1 (6.4 or
5.3 kbps) and G.729 A (8 kbps), or digitizes it according to the G.711 requirements (A-law and µ-law). Compression methods are user-selectable per bundle.
Every six voice timeslots are handled by a single DSP. Each DSP supports one compression method at any time. MT1200 and MT1201 are each equipped with a single DSP, while MT1207 has four and MT12
0xAE has five.
Voice Activity Detection
Voice Activity Detection (VAD) uses digital signal processing techniques to distinguish between silence and speech on a voice connection. VAD reduces the bandwidth requirements of a voice connection by generating traffic only during periods of active voice conversation. With Comfort Noise Generation supported at the remote site, VAD significantly reduces bandwidth consumption without degrading voice quality. VAD achieves additional bandwidth savings when combined with voice compression techniques.
TDMoIP Multiplexing
Compressed voice payload is multiplexed by using the TDMoIP technique. The multiplexing is performed by the MT120xA software. The DSPs send a continuous stream of voice packets; which are put together into a TDMoIP frame by adding
AAL2 headers and a TDMoIP header.

The size of the TDMoIP frame is determined by the following parameters:
• Packetizing interval – The time interval allocated for the TDMoIP frame aggregation (10 to 90 msec).
• Maximum bytes per multiplexed frame – The maximum size of each frame
(100 to 1461 bytes).
The MT120xA continues filling the TDMoIP frame until one of the conditions defined by the above parameters is met.

The 10/100BaseT user LAN port receives Ethernet frames from the user's LAN via the internal Ethernet switch and forwards them to the remote device over the main link. This port supports full duplex transmission with autonegotiation and half duplex with the backpressure option.
Bandwidth Utilization when using TDMoIP
By using TDMoIP multiplexing and the voice activity detection, MT120xA supports a higher number of voice channels over TDM than it is possible by utilizing conventional compression methods alone. TDMoIP multiplexing and grouping the timeslots of compressed voice together into bundles with a common IP address reduces the actual bandwidth used per channel to as low as 4 kbps (up to 16:1), when all channels are active. Better compression, up to 20:1, is achieved when some of the voice channels are idle.
Note
The actual compression achieved at any time depends on the voice activity on the network, the signaling system in use, and the number of modem/fax calls.
The actual bandwidth utilization is determined by the following factors:
• Header sizes:
Ethernet – 18 bytes
IP – 20 bytes
UDP – 8 bytes
TDMoIP – 4 bytes
VLAN (if exists) – 4 bytes.
• Size of the voice packet:
G.723 – 31 bytes (AAL2 header [3 bytes] + voice header [4 bytes] + compressed voice payload [24 bytes])
G.729 – 17 bytes (AAL2 header [3 bytes] + voice header [4 bytes] + compressed voice payload [10 bytes]).
• Packet interval:
G.723.1 – 30 msec
G.729 – 10 msec.
• Number of timeslots in a bundle
• Silence percentage. Studies show that an average person speaks only 40% of the time during a telephone conversation. 50% of the time is spent listening to the other party, while the remaining 10% is spent quietly contemplating.
• Connectivity packets – 64 bytes per minute.
1-12 Functional
Chapter 1 Introduction
Calculating Approximate Bandwidth Utilization (TDMoIP)
Let us calculate an approximate bandwidth for 30 timeslots in one bundle with
G.723.1 compression, 60 % of silence:
{
[(50 x 1000/40) + (30 x 31 x 1000/30 x 0.4)] x 8
}
1000
+ 0.00853 = 109.208 kbps where:
• 50 – size of Ethernet, IP, UDP, TDMoIP headers
• 1000/40 – packet per seconds (pps) transmission rate, calculated according to the packetizing interval chosen (40 msec in this example)
• 30 – number of timeslots
• 31 – size of the compressed G.732 packet plus AAL2 header and voice payload
• 0.4 – 60% of silence
• 8 – conversion from bytes to bits
• 1000 in the denominator – conversion from bits to kilobits
• 0.00853 – connectivity packets rate (64 bytes per minute) converted to kbps.
Bandwidth Utilization when using MPLS
When using non-IP based Ethernet networks or the Serial uplink, the MPLS format can be used instead of the TDMoIP multiplexing format. The MPLS header is smaller than the TDMoIP header (23 rather than 50 bytes), saving about 5% in bandwidth when compared to TDMoIP multiplexing.
The actual bandwidth utilization is determined by the following factors:
• Header sizes:
Ethernet – 18 bytes
MPLSoAAL2 – 5 bytes
• Size of the voice packet:
G.723 – 31 bytes (AAL2 header [3 bytes] + voice header [4 bytes] + compressed voice payload [24 bytes])
G.729 – 17 bytes (AAL2 header [3 bytes] + voice header [4 bytes] + compressed voice payload [10 bytes]).
• Packet interval:
G.723.1 – 30 msec
G.729 – 10 msec.
• Number of timeslots in a bundle
• Silence percentage. Studies show that an average person speaks only 40% of the time during a telephone conversation. 50% of the time is spent listening to the other party, while the remaining 10% is spent quietly contemplating.
• Connectivity packets – 64 bytes per minute.

Management from a
Terminal
The configuration of MT120xA is performed via menu-driven embedded software, using a standard ASCII terminal or a PC running a terminal emulation application connected to the rear panel CONTROL port. Alternatively, you can configure
MT120xA via Telnet connection, which also establishes an inband management link to the remote unit.
4.1 Preparing for the Control Session
This section describes how to prepare MT120xA and the supervisory terminal for the control session.
Control Port Interface Characteristics
MT120xA includes a V.24/RS-232 asynchronous DCE port, designated CONTROL.
The port terminates in an RJ-45 connector. The control port continuously monitors the incoming data stream and immediately responds to any input string received through this port.
The terminal is connected directly to the MT120xA control port. Since terminals usually have DTE interfaces, the connection to the port is made by means of a straight cable, CBL-RJ45/D9/F/STR, supplied with the unit.
Preparing the Terminal
Any standard ASCII terminal (a “dumb” terminal or a personal computer running a terminal emulation application) equipped with a V.24/RS-232 communication interface can be used to configure MT120xA.
Initiating a Control Session
To initiate a control session:
1. Connect the terminal cable to the CONTROL connector on the MT120xA back panel.
2. Connect the terminal cable to the serial port of the control terminal.
3. Turn the control terminal on.
Preparing for the Control Session 4-1
Chapter 4 Management from a Terminal
4. Configure the terminal to the default communication parameters: 9.6 kbps, one start bit, eight data bits, no parity, one stop bit, no flow control, VT100 emulation.
5. Turn MT120xA on.
Levels of Security
MT120xA supports a four-level security and user authentication system:
• Administrator – Allowed to configure all the parameters of MT120xA.
• Operator – Allowed to perform all operations in the system, except for user administration (adding/deleting users, changing user definitions).
• Technician – Allowed to test MT120xA and monitor its operation (for example, monitoring alarms).
• Monitor – Allowed to monitor the MT120xA operation.
The maximum number of users supported by MT120xA is 20. When managing
MT120xA over Telnet, up to five simultaneous management sessions are permitted. Only one administrator is allowed to enter the management session at a time.
MT120xA displays the management menus in accordance with a user’s access rights. For example, configuration screens dealing with the unit configurations are not available to users who logged in as technicians or monitors.
Note
Default Security Configuration
MT120xA is supplied with one administrator account:
• User name: admin
• Password: 12345.
When the first management session is initiated, it is recommended to create a new administrator account, and delete the default one.
•
If the password is lost, consult your local Black Box distributor.

• CAS/Robbed Bit MF – You must configure a signaling profile and signaling table associated with it (ABCD bits, idle code and OOS signals).
• CCS – When working with CCS-SS7, you can configure the fill-in signal unit
(FISU) packets flow by choosing the SS7 keep-alive suppression rate.
•
When changing from CCS to CAS signaling, the MT120xA unit must be rebooted.
Configuring Signaling Profiles
If you are using CAS signaling, you must configure the MT120xA signaling system to make it compatible with the signaling method used by the PBXs connected to the voice T1 or E1 port. The management software allows you to manipulate the
ABCD signaling bits and methods of representation of the idle code and out-ofservice signals generated by the PBXs (see
). Signaling conversion is used
to connect to PBXs that use different signaling formats.
You can store up to five signaling profiles; MT120xA uses only one of them at a time. The signaling profile is configured via the T1/E1 Parameters menu of the
T1/E1 card (see the

Configuring Keep-Alive Suppression Rate
When MT120xA with CCS signaling is connected to PBXs operating with SS7 signaling, the PBXs use one timeslot to transmit signaling information. The signaling information is passed over the signaling link in the form of the following signal units:
• Message signal units (MSUs) provide all signaling associated with call setup and tear down, database query and response, and SS7 network management.
• Link status signal units (LSSUs) provide information on the link status between the network nodes (initiation of link alignment, quality of the signaling traffic etc).
• Fill-in signal units (FISUs) carry no information payload. They occupy the link, when there are no MSUs or LSSUs to send. FISUs are also referred to as
“keep-alive” messages.
Often, in the absence of signaling traffic, the signaling links become flooded with the FISUs, causing communication disruptions. In order to prevent this, you can instruct MT120xA to drop a specified amount of FISUs (up to 90%). You can also disable the FISU dropping by configuring the keep-alive suppression rate to 0%.
This is necessary when working with non-SS7 CCS signaling (for example, ISDN), or if the FISUs are used to acknowledge the receipt of signaling messages. In the latter case, system performance may become unsatisfactory.
To configure the keep-alive suppression rate:
1. From the Signaling Configuration menu (see

4.8 Configuring the Voice Ports
It is recommended to configure the voice port in the following order:
1. Configure the voice port at a bundle level (frame size, destination IP, destination bundle, packetizing interval, TOS parameters, compression method, fax relay, VLAN parameters).
2. Configure the voice port at the physical level (framing mode, restoration time, clock source, interface type, idle code, signaling type, signaling profile).
3. Configure the timeslots (voice or data, mapping to specific bundles, routing to a remote Voice Mux Gateway’s ports and timeslots).
Configuring Bundles
Voice timeslots are grouped together into bundles. MT120xA supports 12 bundles, with a maximum of 31 timeslots per bundle.
Before configuring bundles, you must add at least one bundle.

Chapter 4 Management from a Terminal
Note
MT120xA constantly monitors the status of all connected bundles, by sending 64-byte keep-alive messages to the remote device. Connectivity is confirmed by receiving a reply from the remote unit. This process is similar to pinging remote IP hosts. If a reply is not received, usually due to a main link failure, MT120xA disconnects the bundle and generates the BUNDLE
IS OOS (Out Of Service) alarm. When the BUNDLE IS OOS alarm is generated, MT120xA notifies the PBX by sending “all 1s” string (CCS signaling) or the OOS message (CAS signaling) on all timeslots of the disconnected bundle. This notification allows the attached PBX to stop transmitting over a faulty link and to switch to a backup link.
You can specify the following connectivity parameters:
Connectivity packet rate
(frequency of sending the keep-alive packets, from one packet per 1 second to one packet per 60 seconds)
Connectivity timeout cycles
(number of attempts within which
MT120xA expects to receive at least one reply from the remote device).
For example, if you set the connectivity packet rate to 60 seconds and connectivity timeout to 3, MT120xA disconnects a bundle from which it did not receive at least one reply within 180 seconds.
•
In IP networks, where delays are more common, it is recommended to set the connectivity parameters to their maximum values.

Custom Tone Detection (set tone detection parameters)
Tone Detection–enable/disable tone detection. Enable if the PBX/Voice switch checks the line quality before establishing a call on a specific timeslot. The line is checked by sending a 2000 Hz tone on the line.
Since MT120xA compresses the Voice, the tone is usually also compressed and as a result the PBX may fail to detect the originated
2000 Hz tone. When Tone Detection is enabled, upon detecting a
2000 Hz tone, the DSP sends a message to the remote DSP to generate this specific 2000 Hz tone (tone relaying).
Select Tone–the frequency of the tone to be detected: 2000 Hz.

Diagnostics
This chapter describes the MT120xA diagnostic functions, which include:
• Tone injection (not on MT1201)
• Local and remote loopbacks (not on MT1201)
• Ping utility.
6.1 Tone Injection
The test tone is a data sequence at a rate of 1 kHz. This data sequence is identical to the data sequence that would have been generated if a 1 kHz signal having a nominal level 0 dBm were applied to the input of the channel speech processor.
The tone should be received clearly by the corresponding subscriber connected to the PBX at the nominal receive level. MT120xA supports tone injection towards the local side only (see
The tone injection is activated individually per timeslot. However, multiple tone injections can be run at the same time. MT120xA allows you to set the tone injection timeout causing the tone relay to deactivate automatically after the desired period of time.

Monitoring and Statistics
Collection
This chapter describes the alarms, sanity checks (configuration errors and warnings), main link and voice module statistics supported by MT120xA.
7.1 Alarms
MT120xA detects fault conditions and initiates alarms and events to alert the user:
• Alarms (major and minor) have two statuses, ON and OFF. Alarm status changes to OFF, when a fault condition that caused it is cleared.
• Events have only ON status.
Alarm Buffer
MT120xA maintains two alarm buffers:
• Temporary buffer, represented as the Display All Alarms screen. All alarms, including active alarms, can be deleted from this display.
• Permanent buffer, represented as the Alarm Status screen. Only inactive alarms can be deleted from the Alarm Status screen.
An alarm simultaneously enters both the Display All Alarms log and the Alarm
Status log, and the ALM LED lights to indicate the condition. In addition,
MT120xA displays the ALARM ON indication in the top right-hand corner of the terminal screen. When the event that caused the alarm is cleared, the alarm status changes to OFF, enabling the alarm to be deleted from the permanent buffer.
Working with the Temporary Alarm Buffer
The temporary alarm buffer is represented as the Display All Alarms screen.
To access the Display All Alarms screen:
1. From the Main menu, choose Monitoring.
The Monitoring menu appears (see

7.2 Sanity Checks
Configuration errors and mismatches are rendered by the MT120xA management software as sanity checks. Their main purpose is to maintain the database validity.
MT120xA supports two types of the sanity check messages:
• Error – major configuration error, which prevents the MT120xA database from updating and saving changes.
• Warning – minor configuration error, which allows the user to update the database and save the changes.
Sanity Checks 7-5
Chapter 7 Monitoring and Statistics Collection
Displaying the Sanity Errors and Warnings
Every time you update the MT120xA database, the management software analyses the changes. If a major error is detected, MT120xA aborts the database update and displays the following message:
Data base wasn’t changed. Sanity Error - Check alarm.
If a minor error is detected, MT120xA updates the database and displays the following message:
Sanity Warning - Check alarm.

Boot Manager and Software
Downloading
B.1 Introduction
This chapter describes the MT120xA boot software and provides instructions for software downloading via XMODEM or TFTP applications.
The MT120xA software is stored in the flash memory in two sections: boot and file system. The boot sector holds a boot program that calls up the rest of the program from the file system.
The file system can hold two compressed copies of the MT120xA application software. One copy is referred to as active partition (usually partition 1), the other
– as backup partition (usually partition 0). The active partition is decompressed and loaded into the MT120xA RAM upon power-up. The backup file is used whenever the active file is missing or corrupted.
B.2 Booting MT120xA
MT120xA boots up automatically. After power-up, no user intervention is required, except when the user wants to access the file system to modify or update the MT120xA application software.
Boot Sequence
The following is a description of the boot sequence. If the system is working normally, the entire process is completed within two minutes.
1. The boot program searches for the active partition in the file system. If the file exists, the program continues.
If the file does not exist, the boot program searches for the backup file. If the backup is found, it is used instead of the active partition, and the boot process continues.
If there is no backup file, you must download a file via the XMODEM protocol.
The received file is saved as the active file in the file system.
2. Active and backup partitions are compressed and automatically decompressed into the RAM before execution begins.
3. After decompression, the MT120xA software starts to execute and the user can begin working.
Booting MT120xA B-1
Chapter B Boot Manager and Software Downloading
Accessing the File System
The file system menu is an option that allows the user to perform basic file transfer operations. These operations are all optional.
When working with the File System menu, configure the ASCII terminal rate to
115.2 kbps.
To access the File System menu:
• Press <Enter> several times immediately after powering MT120xA up.
The File System menu is displayed (see

Notes
• Partition information displayed via the File System menu, does not include the
application software of the voice interface. Use the ‘Show Partition Information’ menu (Main Menu > Configuration > System > Show Partition
Information) to display complete information on the MT120xA application software.
• You can also exchange the active and backup partitions via the ‘Set the Active
Application’ menu (Main Menu > Configuration > System > Set the Active
Partition).
B.3 Downloading the Application and Configuration
Software
New application software releases are distributed as *.img files, which are downloaded to MT120xA using the XMODEM protocol or client TFTP application from the File System menu of the boot software. Alternatively, you can download a new software release via TFTP protocol, when the MT120xA management software is already running.
The TFTP protocol can also be used for uploading configuration files which contain the MT120xA database to the management station. Administrators can use this capability to distribute verified configuration files to all other units which use the similar configuration.
Downloading Application Files via XMODEM
Downloading application files using the XMODEM protocol is performed from the
File System menu of the boot software.
To download application file via XMODEM:
1. Configure your ASCII terminal or terminal emulation utility running on your PC to the 115.2 kbps data rate.
2. Access the File System menu (see the
The File System menu appears (see
3. From the File System menu, select Download an application by XMODEM.
MT120xA displays the following message:
Select partition to download
4. Select the backup partition by typing its number, 1.
MT120xA requires confirmation of the partition deletion:
The partition is full. Do you want to erase it (y/n)
5. Type Y.
MT120xA responds with the following string:
Please start the XMODEM download.
Downloading the Application and Configuration Software B-3
Chapter B Boot Manager and Software Downloading
6. Send the *.img file to MT120xA using the XMODEM utility of you terminal application.
Once the downloading is completed, MT120xA saves the new release as an active partition, the former active partition turns into backup, and the boot sequence continues normally.
If a failure occurs during the download, the partially downloaded software is erased. In this case, only active software is left in the Flash memory.
Downloading Application Files using the TFTP Server
Downloading application files using the TFTP server application is performed from the File System menu of the boot software.
1. Access the File System menu (see the
The File System menu appears (see
2. From the File System menu, select System configuration.
3. Enter IP address of MT120xA, and press <Enter>.
4. Enter IP mask of MT120xA, and press <Enter>.
5. Enter default gateway of MT120xA, and press <Enter>.
6. Reset MT120xA.
7. Access the File System menu.
8. From the File System menu, select Download an application by TFTP.
9. Enter the application file name (vmux110.img), and press <Enter>.
10. Enter IP address of the TFTP server, and press <Enter>.
MT120xA starts downloading application software.
MT120xA automatically erases the backup partition (it takes about
25 seconds). Once the downloading is completed, MT120xA saves the new release as an active partition, the former active partition turns into backup.
11. Restart the unit.
B-4 Downloading the Application and Configuration Software
Chapter B Boot Manager and Software Downloading

DC Power Supply Connection – Terminal Block Connector
Note: Ignore this supplement if the unit is
AC-powered.
Certain DC-powered units are equipped with a plastic 3-pin
VDC-IN power input connector, located on the unit rear panel.
Different variations of the connector are shown in Figure 1. All are functionally identical.
Supplied with such units is a kit including a mating Terminal
Block (TB) type connector plug for attaching to your power supply cable.
Connect the wires of your power supply cable to the TB plug, according to the voltage polarity and assembly instructions provided below.
A B C
Caution: Prepare all connections to the TB plug before inserting it into the unit’s VDC-IN connector.
Preparing and Connecting the Power
Supply Cable with the TB Plug
Refer to Figure 2 for assistance.
1. Strip the insulation of your power supply wires according to the dimensions shown.
2. Place each wire lead into the appropriate TB plug terminal according to the voltage polarity mapping shown in Figure 4. (If a terminal is not already open, loosen its screw).
Afterwards, tighten close the three terminal screws.
3. Pull a nylon cable tie (supplied) around the power supply cable to secure it firmly to the
TB plug grip, passing the tie through the holes on the grip.
4. Isolate the exposed terminal screws/wire leads using a plastic sleeve or insulating tape, to prevent the possibility of short-circuit.
5. Connect the assembled power supply cable to the unit by inserting the TB plug into the unit’s
VDC-IN connector until it snaps into place.

Warning:
• Reversing the wire voltage polarity can cause damage to
the unit!
• Always connect a ground (earth) wire to the TB plug’s
Chassis (frame) Ground terminal. Connecting the unit without a protective ground, or interruption of the grounding (for example, by using an extension power cord without a grounding conductor) can cause harm to the unit or to the equipment connected to it!
