T1 RCU MODULE OVERVIEW
The T1 Router Control Unit is a dual board assembly that includes a T1 network interface, DSX-1 PBX interface,
Nx56/64 V.35 interface, and built-in IP router. The T1 RCU can provision, test, and provide status for any card in the channel bank. The faceplate has a DB-9 CRAFT port connection, dual bantam jack connection, plus network, V.35, and Ethernet LEDs. Six access slots allow the user to combine a variety of voice and data services. Up to six Quad
FXS or Quad FXO access modules can be installed to support up to 24 analog voice lines. Other access modules for data applications include the OCU DP and ISDN U-BR1TE. The two remaining access slots support special function cards such as the Echo Canceller Module and the ADPCM compression card.
Used alone, the T1 RCU supports TDM-based applications. Voice over packet/cell applications require that Echo
Cancellation techniques be applied to the voice traffic to achieve high quality voice. With the T1 RCU, a separate
Echo Canceller Module (see the Echo Canceller User Interface Guide, document number 61200384L1-31) must be installed in the special slots (A and B) to accommodate these applications. This module cancels echoes for up to 24 voice ports. It is available with and without Adaptive Differential Pulse Code Modulation (ADPCM).
The T1 RCU can operate in three different modes, depending upon the firmware loaded: Channel Bank, Switchboard, and Voice over ATM (with the Echo Canceller). Firmware can be updated by using XMODEM transfer protocol via the base unit’s CRAFT
port or by using TFTP from a network server. (See Appendix A. Updating TA 850 Firmware
tion.)
Only the first two dipswitches on the RCU are used. With the first dip switch down (to the right of the unit if you are facing it), the unit boots up in a mode to update the firmware. With the second dip switch down, the unit factory defaults at startup.
The terminal menu is the access point to all other operations. Each terminal menu item has several functions and submenus that identify and provide access to specific operations and parameters. These menu selections are described later in this User Interface Guide.
See Appendix C for instructions about navigating the terminal menus.
2.
VOICE OVER ATM OVERVIEW
Voice over ATM (VoATM) is the technology used to transmit voice conversations over a data network using Asynchronous Transfer Mode (ATM). There are several potential benefits to moving voice over a data network using ATM.
First, the small, fixed-length cells require lower processing overhead. Second, these small, fixed-length cells allow higher transmission speeds than traditional packet switching methods.
ATM allocates bandwidth on demand, making it suitable for high-speed connection of voice, data, and video services.
Conventional networks carry data in a synchronous manner. Because empty slots are circulating even when the link is not needed, network capacity is wasted. ATM automatically adjusts the network capacity to meet the system needs.

VOICE OVER ATM APPLICATION
You can upgrade the T1 RCU for VoATM by adding the Echo Canceller (see the Echo Canceller User Interface
Guide, document number 61200384L1-31). The Echo Canceller is used in ATM voice applications that require G.168
echo cancellation. The RCU must be using Voice Over ATM firmware to be able to use this module. The module is available with and without ADPCM.
Figure 1 shows a typical VoATM application. The TA 850 connects to the ATM Network to provide both voice and high speed data from a single platform.

INSTALLING A MODULE
After installing the TA 850 Base Unit and connecting the required cables, you can install necessary modules.
Remove the 20 Hz fuse before exposing backplane or accessing channel units.
Electronic modules can be damaged by static electrical discharge. Before handling modules, wear an antistatic discharge wrist strap to prevent damage to electronic components. Place modules in antistatic packing material when transporting or storing. When working on modules, always place them on an approved antistatic mat that is electrically grounded.
Individual access modules insert from the front. A locking bar holds the modules in place for added security. Disengaging the captured screw allows removal of the locking bar. All wiring connections terminate on the backplane.
The following step/action table tells how to install a module.

>Network Time
The TA 850 unit time can be entered manually from the S YSTEM I NFO menu, or the unit can receive time from an NTP/
SNTP server. The N ETWORK T IME menu includes all parameters relating to how the unit communicates with the time server.
Server Type
The server type defines which port the TA 850 will listen on to receive timing information from the time server.
NT Time
The TA 850 will receive time from an NT server running SNTP software on its TIME port.
SNTP
The TA 850 will receive time directly from an SNTP server.
Active
This network timing feature can be turned on and off. It determines whether the unit will request and receive time from a time server.
Time Zone
There are several time zones available for the time to be displayed in. All time zones are based off of Greenwich Mean Time (GMT).
Adjust for Daylight Saving
Since some areas of the world use Daylight Savings Time, theTA 850 is designed to adjust the time on the first Sunday in April and the last Sunday in October accordingly if this option is turned on.
Host Address
This is the IP address of the time server that theTA 850 will request and receive time from.
Refresh
This is the interval of time between each request theTA 850 sends out to the time server. A smaller refresh time guarantees that the unit receives the correct time from the server and corrects possible errors more quickly, but it is more taxing on the machine. A range of refresh times is available for the user to decide which is best for their unit.
Status
This displays the current status of the time negotiation process. If an error is displayed, check all connections and configurations to try to resolve the problem.

>Upgrade Firmware
Updates firmware when TA 850 enhancements are released. Two transfer methods are available for use in updating the TA 850 system controller.
Transfer Method
The two methods for upgrading are XMODEM and TFTP.
(See Appendix A. Updating TA 850 Firmware
using XMODEM on page 53 and Appendix B. Updating TA 850 Firmware using TFTP on page 57 for more
information.) TFTP requires a TFTP server running somewhere on the network. The TA 850 starts a TFTP client function which gets the upgrade code from the TFTP server. Selecting XMODEM will load the upgrade code through the CRAFT port using any PC terminal emulator with xmodem capability.
TFTP Server Address
This is required when the transfer method is TFTP. It is the IP address or domain name (if DNS is configured) of the TFTP server.
TFTP Server Filename
This is required when the transfer method is TFTP. It is the case-sensitive file name which contains the upgrade code.
Transfer Status
This appears when TFTP is used. It displays the status of the transfer as it happens. Any error or success message will be displayed here.

Proxy ARP
This feature allows the network portion of a group of addresses to be shared among several physical network segments. The ARP protocol provides a way for devices to create a mapping between physical addresses and logical IP addresses. Proxy ARP makes use of this mapping feature by instructing a router to answer ARP requests as a "proxy" for the IP addresses behind one of its ports. The device which sent the ARP request will then correctly assume that it can reach the requested IP address by sending packets to the physical address that was returned. This technique effectively hides the fact that a network has been (further) subnetted. If this option is set to Y
ES , when an ARP request is received on the Ethernet port the address is looked up in the IP routing table. If the forwarding port is not on the
Ethernet port and the route is not the default route, the 850 will answer the request with its own hardware address.
MAC Address
This is a read-only MAC address programmed at ADTRAN.

By enabling port translation, IP packets are modified as they pass through this interface. During transmission, private addresses are translated into a single public (NAPT) IP address. Incoming packets are translated from the public to private address based on the protocol port numbers. Once enabled, you must set up NAT for use.
The port translation requires at least a single real IP address for translating. This value can use the IP assigned to the interface (or assigned via layer 2 protocol like PPP), obtained using DHCP client, or statically specified on this menu. If the address cannot be learned, then it must be specified in order for the translation to work.
Add translation entries to "fine tune" special protocols or specify private addresses.
The public IP address used for this translation entry can be the NAPT IP address assigned to the link or can be specified. You specify an address to direct packets with certain protocols to different servers.
The upper layer protocol that is to be monitored for translation. For TCP and UDP, a port number must also be specified.
The public destination port associated with this entry can be specified to add more control over certain types of traffic. The default, A NY P ORT , covers all port types.
The private IP address can be specified to steer certain protocols and ports to specific servers in the private network. Likewise, internal hosts can be steered to certain servers on the public network. A new request from the public network matching this entry’s public parameters will be dropped if this mode is set to A NY I NTERNAL .
The private destination port associated with this entry can be specified to add more control over certain types of traffic. Leave as A

ORT to cover all port types.
By default, the application payload in the packet is scanned for occurrences of the private/public IP address in binary or ASCII form. Set this to No for applications where this will cause problems.

Appendix A. Updating TA 850 Firmware using XMODEM
The TA 850 supports firmware updating using XMODEM transfer protocol via the base unit’s CRAFT port. XMO-
DEM is found in the VT 100 terminal emulation application in the ADTRAN Utilities package and in most PC VT
100 communications software packages.
Make certain that the communications software package being used has flow control turned off.
Before beginning this procedure, you must obtain the appropriate update file from ADTRAN Technical Support at
(888) 4ADTRAN (423-8726).
An XMODEM download can be initiated by enabling the appropriate dip switch or by using the console menus. The following materials are required.
• VT 100 terminal or PC with VT 100 terminal emulation software
• XMODEM software
To prevent electrical shock, do not install equipment in a wet location or during a lightning storm.
Electronic modules can be damaged by static electrical discharge. Before handling modules, wear an antistatic discharge wrist strap to prevent damage to electronic components. Place modules in antistatic packing material when transporting or storing. When working on modules, always place them on an approved antistatic mat that is electrically grounded.
Updating Firmware via the Dip Switch
Perform the Steps Below in the Order Listed
1.
Using a VT 100 terminal emulation communication software package which contains XMO-
DEM protocol support, log in to TA 850. Set the transmit rate of the emulation software to
9600 baud.

The dip switch is red and is located at the top edge of the card.
Only the first two dipswitches on the RCU are used. With the first dip switch down (to the right of the unit if you are facing it), the unit boots up in a mode to update the firmware. With the second dip switch down, the unit factory defaults at startup.
3.
Press Enter until a menu appears.
To shorten transmit time, select the option from the menu to change the transmit rate to 115.2 baud or the highest rate supported by the terminal emulation software. If this transmit rate is changed, change emulation software properties to match this rate and disconnect and connect again. Press
Enter again until the menu appears.
4.
5.
Choose option 1, B EGIN XMODEM D OWNLOAD N OW , from the menu to start the XMODEM file download.
Press Y at the S TART F LASH D OWNLOAD N OW prompt to continue with the XMODEM file transfer.
When TA 850 is ready to receive the XMODEM upload, the menu screen will display Transmit
Flash . . . download file now . If this does not appear, please review the steps above for possible configuration errors.
6.
From the terminal emulation software, begin the XMODEM upload by using the appropriate command sequence. (If necessary, refer to terminal emulation software documentation for help. Also, when specifying the filename, ensure that the file transferred is the one provided by ADTRAN. Otherwise, the update will not complete successfully.)
Because XMODEM data is being transferred in-band through the menu interface, the VT 100 menus of TA 850 will be inoperable from the CRAFT port.

Appendix F. RFC1483 Quick Start (IP Routing with NAT)
To illustrate the use of NAT, consider the example from Appendix C. To set up a single public address that will be used to access the public network, you will use the NAT menu on the WAN/ATM/RFC1483 IP menu.
IP Routing with NAT
Step
1
Action
From the NAT menu, set N ETWORK A DDRESS P ORT T RANSLATION to
E NABLED . (This will enable translation and allow you to enter the NAT options.)
2
Set P UBLIC IP A DDRESS M ODE to S PECIFIED so you can enter your public address. During transmission, private addresses are translated into this public (NAPT) address.
You will also need to set up the Translation Table to do translation on the body of the packets for certain protocols, such as FTP, to work correctly.

From the T RANSLATION T ABLE menu, create a new entry by arrowing into the table.
For P UBLIC A DDRESS M ODE , select NAPT A DDRESS to use the previously specified public address.
For P ROTOCOL , select TCP.
Make sure that T RANSLATE B ODY is set to Y ES .

Appendix G. RFC1483 Quick Start (Bridging)
The TA 850 allows for complete integration of voice and data delivery from one compact platform. Once you have completed the voice turn up procedure from the previous example, adding data to the circuit requires some additional setup.
To configure a TA 850 for Bridging, you need to know the VPI and VCI values for the data circuit on your network.
