Channel Service Unit (CSU) to the MultiVoice Gateway. If the T1 transceiver in the MultiVoice Gateway does not have an internal CSU, it can connect to a T1 line no longer than 655 feet. Anything of greater length requires an internal CSU. The value should reflect the longest line length you expect (up to a maximum of 655 feet).
Page 75: Understanding The Channel Configuration Parameters
When configuring ISDN PRI service for your MultiVoice Gateway units, you must configure ISDN signalling for the line. Optionally, you can also configure the MultiVoice Gateway to send either ISDN code 16 (Normal call clearing) or code 17 (User busy) when the PRI switch servicing the MultiVoice Gateway triggers the T310 timer.
Page 76: Configuring A Line For Robbed-Bit Signalling
If a call is presented to the MultiVoice Gateway, and there is an extended period of delay while the call is being set up (for example, local Ethernet traffic slowing down RADIUS requests or DNS lookups), you might want your users to get a disconnect indication other than the generic Normal call clearing.

Note: When an ISDN call disconnects in Germany, the ISDN switch sends call billing information to the call originator as part of the call tear-down process. For lines that use the German 1TR6 switch type, you can access ISDN call charges in the Ascend Enterprise MIB via SNMP management utilities.
Page 95: Chapter 6 Configuring Multivoice
Additionally, you may improve MultiVoice call performance by: • Entering an IP address for a secondary MultiVoice Access Manager. • Adjusting the frequency and time intervals when a MultiVoice Gateway must register with the MultiVoice Access Manager. • Enabling use of a fixed or dynamic Jitter Buffer.
Page 96: Configuration Options
Near End Cut Through=Yes Single Dial Enable=No You must provide an IP address for the GK IP Adrs parameter for the MultiVoice Gateway to process voice calls. This address points to the computer running the MultiVoice Access Manager that will perform all of the Gatekeeper functions for this Gateway. The MultiVoice Gateway can process calls over must IP networks using the factory defaults for the remaining VOIP Options parameters.
Page 97: Controlling Keep-Alive Registration
MultiVoice Gateway is operating in backup mode. • If the IP address for 2nd GK IP is null, then the MultiVoice Gateway goes into a slow poll mode with the MultiVoice Access Manager at GK IP Adrs. Reregistration policy parameters After a MultiVoice Gateway registers with the MultiVoice Access Manager at 2nd GK IP, it periodically attempts to reregister with the MultiVoice Access Manager at GK IP Adrs.

The Single Dial Enable parameter is used to enable/disable single stage dialing of MultiVoice calls. Setting this value to Yes enables the MultiVoice Gateway to extract the Dialed Number Identification Service (DNIS) string from a single dialed entry. Setting this value to No disables DNIS string collection, requiring users to dial the MultiVoice Gateway, first, wait for a dial tone form the MultiVoice Gateway, then dial the called telephone number.

Can indicate the number of a slot containing a modem card and the modem on that card, or the virtual slot of the MultiVoice Gateway unit’s bridge/router. If the slot is virtual, the port number represents a virtual interface to the bridge/router, starting with 1 for the first session of a multichannel session.
Page 208: Snmp Administration Support
An SNMP manager must be running on a host on the local IP network, and the MultiVoice Gateway must be able to find that host through either a static route or RIP. SNMP has its own password security, which you should set up to prevent reconfiguration of the MultiVoice Gateway from an SNMP station.
Page 209: Setting Community Strings
Information held in the Ascend Events Group is erased and its values are initialized when the MultiVoice Gateway is reset by software or by toggling the power off and on. The SNMP object sysAbsoluteStartupTime is the time in seconds since January 1, 1990, and is not modified.
Page 210: Setting Snmp Traps
To specify the community string for communicating with the SNMP manager, set the Comm field to the community name associated with the SNMP PDU. The next three fields specify whether the MultiVoice Gateway traps alarm events, port events, and/or security events, respectively, and sends a trap-PDU to the SNMP manager.

PRI and BRI interface requirements and lists cabling pin-outs. If the cabling is not the problem and the MultiVoice Gateway is a T1 unit, ensure that the value of the Buildout parameter or the Length parameter in the Line profile matches the actual distance in your configuration.
Page 227: The Net/Bri Lines Do Not Dial Or Answer Calls
In some countries outside the U.S., it is common for no logical link to exist before the MultiVoice Gateway places a call. In the U.S., when you first plug a line into the MultiVoice Gateway or switch power on, the central office switch can take as long as 15 minutes to recognize that the line is now available.
