When both passwords are set, the enable secret password takes precedence over the enable password. To remove a password, use the no form of the commands: no enable password or no enable secret password. For more information about password recovery procedures for Cisco products, see http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/ products_tech_note09186a00801746e6.shtml.
Page 34: Abbreviating Commands
Using the CLI Abbreviating Commands Typing a complete command name is not always required for the command to execute. The Cisco IOS CLI recognizes an abbreviated command when the abbreviation contains enough characters to uniquely identify the command. For example, the show version command can be abbreviated as sh ver. It cannot be abbreviated as s ver because s could mean show, set, or systat.
Page 35: Using The Debug Command
For commands that are enabled by default and have default settings, the default form enables the command and returns the settings to their default values. The no and default forms of commands are described in the command pages of Cisco IOS software command references.

Page 41: Verifying Basic Setup On The Cisco Vgd 1T3 Voice Gateway
Cisco IOS commands write terminal and show running-config will always show GigabitEther. Analyzing the System Boot Dialog The Cisco VGD 1T3 voice gateway has a specific boot sequence. To view the boot sequence through a terminal session, you must have a console connection to the gateway before it powers up.
Page 42 If you observe no messages on the console port, verify that the baud rate is configured correctly. The Cisco VGD 1T3 console port can support a baud rate up to 115200. The following boot sequence occurs. Numbers and comments are inserted in the example to describe the boot sequence.
Page 43 Therefore, the software asks, “Would you like to enter the initial configuration dialog? [yes/no]” Enter no. In this example, the Cisco IOS software is configured manually. The automatic setup script is not used. Configuring the Cisco IOS software manually develops your expertise.

Page 60: Configuring A Channelized T3 Feature Card
Configuring a Channelized T3 Feature Card The Cisco VGD 1T3 voice gateway supports the channelized T3 (CT3) feature card only. The CT3 card offers 28 individual T1 channels (bundled in the T3 line) for serial transmission of data. The channelized T3 link supports the maintenance data link channel in C-Bit parity mode and also payload and network loopbacks.
Page 61: Examples
Channelized T1 ISDN PRI offers 23 B channels and 1 D channel. Channel 24 is the D channel for T1. Request PRI Line and Switch Configuration from a Telco Service Provider Before configuring ISDN PRI on your Cisco router, you need to order a correctly provisioned ISDN PRI line from your telecommunications service provider.
Page 62: Controller Numbering
• Determine if the outgoing B channel calls are made in ascending or descending order. The Cisco IOS software default is descending order; however, if the switch from the service providers is configured for outgoing calls made in ascending order, the router can be configured to match the switch configuration of the service provider.

Page 66 The D channel notifies the central office switch to send the incoming call to particular time slots on the Cisco gateway or router. Each one of the B channels carries data or voice. The D channel carries signaling for the B channels. The D channel identifies whether the call is a circuit-switched digital call or an analog modem call.

Page 101: Configuring Voice Over Ip
Configuring Voice over IP The information in this chapter applies to configuration of Voice over IP (VoIP) on the Cisco VGD 1T3 voice gateway. VoIP technology enables voice-capable routers and switches to transport packetized live voice traffic such as telephone calls over IP data intranetworks or internetworks rather than public switched telephone networks (PSTN) or private TDM (PBX) networks.
Page 102: Voip Basics
Although VoIP technology is primarily software-based, it requires that you install a universal port or Note voice feature card into the appropriate slot of your Cisco VGD 1T3 voice gateway. The number of ports or channels available for sending VoIP data depends on the capacity of your card.

Enabling QoS Features for VoIP Call-Admission Control You can gracefully prevent calls from entering your Cisco VGD 1T3 voice gateway from the PSTN when certain resources—such as CPU, memory, and interfaces—are not available to process those calls. Such intervention is called call-admission control.
Page 116: Other Bandwidth-Reduction Features
If your calls are subject to significant toll-office processing, choose PCM if you have sufficient bandwidth. We also recommend that you employ a Cisco IOS Multimedia Conference Manager (H.323 gatekeeper) or management application such as Cisco Voice Manager to help manage these types of processes.

H.323. MGCP simplifies the configuration and administration of voice gateways and supports multiple (redundant) call agents, eliminating the potential for a single point of failure in controlling the Cisco IOS gateway in the network.
Page 129: Configuring Mgcp Gateway Support
MGCP uses endpoints and connections to construct a call. Endpoints are sources of or destinations for data and can be physical or logical locations identifying a device. The voice ports on the Cisco MGCP gateway are its endpoints. Connections can be point-to-point or multipoint. Cisco Unified Communications Manager acts as the MGCP call agent, managing connections between endpoints and controlling how the Cisco IOS gateway functions.

MGCP gateway. Switchover (Failover) Cisco IOS gateways can maintain links to up to two backup Cisco Unified Communications Manager servers in addition to a primary Cisco Unified Communications Manager. This redundancy enables a voice gateway to switchover to a backup if the gateway loses communication with the primary. The backup server takes control of the devices that are registered with the primary Cisco Unified Communications Manager.
Page 134: Switchback
The gateway processes calls on its own using H.323 until one of the Cisco Unified Communications Manager connections is restored.
Page 135: Mgcp Gateway Registration With Cisco Unified Communications Manager
When the fallback mode is in effect, the affected MGCP gateway repeatedly tries to open a TCP connection to a Cisco Unified Communications Manager server in the prioritized list of call agents. This process continues until one of the Cisco Unified Communications Manager servers in the prioritized list responds.

Page 161: Using Cisco Unified Communications Manager To Configure Transcoding And Media Termination Point
This chapter describes the steps for enabling transcoding and media termination point (MTP) support on Cisco VGD 1T3 voice gateways in a Cisco Unified Communications Manager network. This feature provides enhanced multiservice support by enabling transcode functions and MTP in voice gateway routers.
Page 162: Dsp Resources
Restrictions for Transcoding and MTP for the Cisco VGD 1T3 Voice Gateway DSP Resources The Cisco VGD 1T3 voice gateway uses PVDM2 modules to provide DSP resources for transcoding and hardware MTP services. Use Cisco Unified Communications Manager 5.0 (formerly known as Cisco CallManager 5.0) or later for transcoding and for MTP.
Page 163: Dsp Farms
The details of whether DSP resources are used, and which DSP resources are used, are transparent to Cisco Unified Communications Manager. The DSP farm uses the DSP resources in network modules on Cisco routers to provide transcoding and hardware MTP services.
Page 164: Media Termination Point
• same G.711 codec but a different packetization time. The repacketization requires a DSP resource so it cannot be done by software only. Cisco Unified Communications Manager also uses the term software MTP when referring to a hardware MTP. For MTP and transcoding, the DSP farm supports only two IP streams connected to each other at a time.
Page 165: Allocation Of Dsp Resources Within The Dsp Farm
DSP resources can reside in packet-voice DSP modules (PVDM2s) installed in voice network modules or directly in the network module. Cisco VGD 1T3 voice gateway routers have onboard DSP resources located on PVDM2s installed directly on the motherboard. Your router supports up to six voice network modules.
