Introduction
This document describes menu items in D.04.07.22 software and important configuration parameters for
interoperating with various media gateway controllers, gateways and feature servers. This document
assumes that configuration has already been completed for data connectivity, either across the WAN or the
Ethernet.
For further configuration assistance, please contact ADTRAN technical support at 888-423-8726.

Modem / Fax Calls
Modem and fax machines will operate with both ADPCM and PCM. Modem upspeed (i.e. dynamic
compression) functionality is supported with Nuera, Metaswitch, and General Bandwidth. Other vendors do
not currently support this feature. Adaptive Clocking must be enabled for proper modem / fax operation
when using the 10/100 BaseT Ethernet interface as the connection to the WAN. Adaptive Clocking
should be disable if the T1 interface is used to connect to the WAN.

Configuration
The MGCP Configuration and MGCP Endpoint Config menus will appear once MGCP is selected as the
call control.

Below is a screen capture of the MGCP Configuration menu. Descriptions for each of the parameters follow.
MGCP Configuration Menu Parameter Descriptions:
Standard
MGCP 1.0bis (RFC3435) - The latest MGCP standard
MGCP 0.1 / NCS 1.0 – Older version of MGCP or the PacketCable™ derivative
MGC Address
No default. Address of call agent. Fully Qualified Domain Name (FQDN) or IP
address.
Local Address
No default. IAD’s IP address. This should match interface address (PPP or Ethernet
for example). This can be configured as an IP address or FQDN.
MGC UDP Port
The default is 2727. Destination Port when contacting Call Agent.
Local UDP Port
The default is 2427. The port on which the IAD listens for messages.
ADPCM Coding
IETF (RTP) or ATM Forum. IETF (RTP) is the default. This adjusts the nibble order
for packing ADPCM bytes. The ATM-Forum setting is required for both BroadSoft
and Nuera.
RFC 2833
The default is None since most VoIP implementations do not care about ABCD
signaling. Other options include “RTP Payload Type 94” (supported for Lucent
iMerge) and “RTP Payload Type 127” (supported for Nuera RDT-8).

DSCP Signaling
This decimal value represents the upper 6 bits of the IP ToS for call control
messaging.
DSCP RTP Traffic
This decimal value represents the upper 6 bits of the IP ToS for RTP voice payloads.
This setting will be ignored if the call agent provides non-zero value for the DSCP.
Advanced Config
See below.
The MGCP Configuration menu contains a sub-menu entitled Advanced Config. The Advanced Config
menu is shown in the screen capture below. Descriptions for each of its parameters follow.
Advanced Config Menu Parameter Descriptions:
Retransmit Delay
The time between retransmissions of MGCP messages. The default uses the
algorithm described in RFC 3435. Available delay times include 100ms, 250ms,
500ms, 1 sec, 2 sec and 4 sec.
Max 1
The number of retransmissions allowed before attempting alternate MGC addresses.
5 “Suspicion threshold” as defined in RFC 3435.
Max 2
The number of retransmissions before an endpoint becomes disconnected from the
call agent. Max 2 must always be larger than Max 1. 7 “Disconnection threshold” as
defined in RFC 3435.

Default Pkt Period
In the event that the call agent does not provide a packetization period, the IAD will
default to the selected value. Values include 10ms, 20ms and 30ms. The default
value is 20ms. Note: If a packetization period is provided by the call agent, the IAD
will always use the call agent provided value.
UDP Reply Method
The default selection is Foreign Source Port. This parameter should not be changed.
This parameter was added for a very specific custom application.
Voice Bearer
The default selection is RTP/IP. Standard VoIP applications use RTP/IP as the
transport. However, the Total Access 600 series IADs also support ATM/AAL2
media transport under MGCP control for very specific custom applications.
RTP/UDP Rx Method The default selection is Normal. In ‘Normal’ mode, the RTP receive process will
match incoming packets with the UDP port and IP address of active connections
before accepting the packet. In ‘Promiscuous’ mode, only the IP address will be
verified. Broadsoft is currently the only vendor that requires ‘Promiscuous’ mode.
Persistent Ntfy
The default selection is Off. With this mode disabled, this means the IAD will not
send notifications in the NTFY of hang-up (hu), off-hook (hd), or hook-flash (hf), if it
has not first received the request for this event in a Notification Request (RQNT).
Options are hd, hu, hf, and combinations of each. If the events are selected, this
means the IAD will send out a NTFY for this event, even if it has not received an
RQNT for this requested event. Persistent Ntfy is currently needed for
interoperability with Broadsoft, namely hd, which is needed for initial dial tone once
the link has become active.
Bracketed IP
The default selection is Yes. This means per RFC 3435 that the endpoint name will
use the convention ‘endpointname@[x.x.x.x]. Some call agents do not support the
bracketed format. With the option set to No, this changes the format to
‘endpointname@x.x.x.x’ (notice the brackets are no longer included). Certain
versions of Cisco BTS require that the brackets be removed.

The MGCP Endpoint Config menu contains configuration options for every analog port and DSX endpoint on
the Total Access 6xx IAD. This menu allows the user to select a preferred CODEC on a port by port basis. It
also contains options for programmable endpoint names.
Endpoint Config Menu Descriptions:
Preferred CODEC
There are three options available: No Preference, PCM (G.711), ADPCM (G.726).
These options change the order in which the IAD offers its preferred CODEC type.
Default of No Preference means it will offer ADPCM (type 2), then PCM(type 0). If
the preferred type is set to PCM, then the offered order changes from "2 0" to "0 2".
Name
This allows the user to configure each endpoint based on preferential naming
convention. The standard is aaln/# for analog ports and ds/ds1-1/# for the DSX
interface. This supports 17 alpha-numeric characters.

Status Screens
The Total Access IADs contain numerous screens that allow the user to see the current status of various
events. Below is an example of the MGCP Endpoint Statistics menu.
Endpoint Stat
“Disconnected” – The endpoint has not verified connection with the call agent.
“Restarting” – The endpoint is sending “rsip” messages and is waiting for a response
from the call agent.
“Connected” – The endpoint has been acknowledged by the call agent.
RTP Tx Count
The number of RTP packets transmitted
RTP Rx Count
The number of RTP packets received
RTP Rx Seq Num Errs RTP Packets arriving with an unexpected sequence number
Other status screens are shown below.

Gateway Stats screen:
It only takes endpoint 1 to connect to the call agent in order for the Gateway Link to show UP and the Voice
LED on the unit to illuminate GREEN.

Fractional T1 Support Configuration Screen
The T1 versions of the Total Access 600 series IADs have the ability to limit bandwidth at the physical layer.
Fractional T1 circuits can be used with the IAD by configuring the total number of DS0s in the T1/Config
section of the Interfaces menu as shown below:
A minimum of 12 DS0’s must be configured in order to ensure proper QoS for voice traffic when using PPP as
the layer 2 protocol. No such restriction is imposed when using ATM as the layer 2 protocol. This restriction
will be removed once packet fragmentation and interleaving are supported.
To configure the IAD for fractional T1 operation, set the Fractional T1 configuration parameter to Manual.
Another menu item will appear to allow the user to configure the number of DS0’s in the fractional T1 circuit.
Traffic begins at the first DS0 on the T1.
Fractional T1
“Disable” – The IAD uses the full T1.
“Manual” – Allows the user to enter the number of DS0’s used in the fractional T1
circuit.
# DS0’s
The number of DS0’s used in the factional T1 circuit. The fractional T1 circuit begins
at DS0 1. 12 is the minimum value when using PPP as the layer 2 protocol. No such
restriction is imposed when using ATM as the layer 2 protocol.
