Integrated Voice and Data WAN on T1/E1 Interfaces Using the AIM-ATM-VOICE-30 Module

---

This document provides configuration enhancements for the AIM-ATM-VOICE-30 digital signaling processor (DSP) card on the Cisco 2600 series, Cisco 2600XM, Cisco 3660, Cisco 3725, and Cisco 3745. This feature provides a voice processing (termination) solution with AIM-ATM-VOICE-30 at a density of 30 Voice over IP (VoIP) or Voice over Frame Relay (VoFR) voice or fax channels, while not consuming a network module slot.

This feature adds the following benefits:

•Integrated voice and serial data WAN functionality on the same T1/E1 interface or on the second port of the voice/WAN interface cards (VWIC)

•Support for high-complexity codecs

The serial interface supports the following features:

•Point-to-Point Protocol (PPP), Frame Relay (FR), and high-level data link control (HDLC) encapsulations—Up to 120 channels

•FR, HDLC, and PPP encapsulation and voice on the same T1/E1 voice interface available in the following two options:

–Channel associated signaling (CAS) or Primary Rate Interface (PRI) group, plus the channel group are defined on the same T1/E1 interface in the Cisco 2600 WIC slot.

–The DS0 or PRI, plus the channel groups are configured across two ports of the same T1/E1 VWIC. For example, you can configure a DS0 group or a PRI group on port 0, and a channel group on the same port or another port.

•HDLC data inversion—Meets the density requirement for T1 links

•Compression support—Software and hardware compression is supported on the Cisco 3660, Cisco 3725, and Cisco 3745

---

Note There is only one Advanced Integration Module (AIM) slot on Cisco 2600 platforms, so hardware compression is not applicable to the Cisco 2600 series.

Information About Integrated Voice and Data WAN on T1/E1 Interfaces Using the AIM-ATM-VOICE-30 Module

Before you configure the Integrated Voice and Data WAN on T1/E1 Interfaces Using the AIM-ATM-VOICE-30 Module feature, you must first understand the following concepts:

•AIM-ATM-VOICE-30 Module

•Integrated Voice and Data WAN

•High-Complexity Voice Compression

•Related Features and Technologies

AIM-ATM-VOICE-30 Module

The AIM-ATM-VOICE-30 module is an advanced integration module capable of supporting up to 30 voice or fax channels when used in a Cisco 2600 series, Cisco 2600XM, Cisco 2691, Cisco 3660, Cisco 3725, and Cisco 3745 with one of the T1/E1 voice/WAN interface cards (such as VWIC-1T1). The AIM-ATM-VOICE-30 module includes DSPs that are used for a number of voice processing tasks such as voice compression and decompression, voice activity detection or silence suppression, and private branch exchange (PBX) or public switched telephone network (PSTN) signaling protocols.

By using the AIM-ATM-VOICE-30, you can support VoIP, VoFR, or VoIP over ATM (VoATM) while leaving the router network module slot open for other functions such as asynchronous or synchronous serial concentration. Refer to the AIM-ATM, AIM-VOICE-30, and AIM-ATM-VOICE-30 on the Cisco 2600 Series and Cisco 3660 feature document for more information.

Integrated Voice and Data WAN

This feature adds integrated voice and serial data WAN service on the same T1 or E1 interface or VWIC on AIM-ATM-VOICE-30 DSP cards. This enhancement enables you to use some DS0 channels for serial data FR, HDLC, and PPP, for example, while the remaining T1 or E1channels can be used for voice CAS or PRI.

Figure 1 shows a typical application scenario. Your ability to integrate voice and serial data on the same T1 or E1 line minimizes the recurring cost of providing PSTN and data WAN access. In particular, integrated access provides a number of voice DS0s (for PSTN access) and a Frame Relay link on the same T1.

Figure 1 Typical Application Scenario

Figure 2 shows a typical deployment scenario in which port 0 of the VWIC-MFT module is connected to a service provider with 20 channels. These 20 channels are used for voice (running CAS or PRI), while the remaining four channels are used for serial data (running Frame Relay). Using this type of configuration, you can take advantage of the integrated service offered by a service provider and minimize the cost of leasing and supporting T1 or E1 lines.

Figure 2 Typical Feature Deployment

High-Complexity Voice Compression

This feature adds high-complexity G.723 and GSM-FR codec support to the AIM-ATM-VOICE-30 card so that the DSP can support both medium- and high-complexity codecs running separately. Each DSP core can process a maximum of two voice channels, so each AIM-ATM-VOICE-30 module can support up to 16 voice channels when running a high-complexity DSP firmware image.

The following high-complexity codecs are supported:

•G.723.1 5.3K

•G.723.1 6.3K

•G.723 1A 5.3K

•G.723 1A 6.3K

•G.729

•G.729B

•GSM-FR

The following medium-complexity codecs are supported in high-complexity mode:

•G.711ulaw

•G.711alaw

•G.726

•G.729A

•G.729 AB

•Clear-channel codec

•Fax relay

---

Note Neither modem-relay nor GSM-EFR is supported.

Configuring Network Clock Source and Participation

---

Note You must configure network clock source and participation to use the Integrated Voice and Data WAN on T1/E1 Interfaces Using the AIM-ATM-VOICE-30 Module feature.

---

Packet voice and video are sensitive to time delays. To prevent mismatches and data slips, you must synchronize data flows to a single clock source, known as the network clock. When a network clock is configured on a gateway, the router is externally clocked by one T1 or E1 port and passes that clock signal across the backplane to another T1 or E1 port on another WIC or network module slot. Use of a network clock on a gateway is configured by naming the network modules and interface cards that are participating in network clocking, and then selecting a port to act as the source of timing for the network clock.

The network clock provides timing from the source, through the port to the AIM, and then out to all participating router slots. The Cisco 2600 series and Cisco 2600XM support one internal AIM slot, and the Cisco 3660, Cisco 3725, and Cisco 3745 support two internal AIM slots.

Network Clocking Commands

Three commands configure network clocking: network-clock-participate, network-clock-select, and clock source (digital ports only).

The network-clock-participate command configures the specified router slot to take its clock from the network clock; that is, this command identifies the slots that get their timing from the AIM.

The network-clock-select command is used if the clock is from an external source.This command configures a port in one of the participating slots to be a source for the network clock, and assigns it a priority level. This command is repeated for each port that you want to act as a primary or backup source for the network clock. The highest priority level indicates the port that you want to be the primary source of timing for the network clock. If the highest-priority port becomes unavailable, the second highest priority level takes over automatically as the network clock, and so forth for the lower-priority levels. The clocking is provided to the AIM, which then provides it to participating slots in the router.

Network Clocking Prerequisites

The network clock source must be derived from an external source, for example, PSTN, PBX, or an ATM network. For digital voice ports, the clock source command in controller configuration mode configures the type of timing (internal or from the line) for each port that you designate as a primary source or backup for the network clock.

These commands allow maximum flexibility. For example, on a router with a multiflex trunk VWIC connected to an ATM network and a digital T1/E1 packet voice trunk network module connected to a PBX, you could set up network clocking in any of three ways:

•The multiflex trunk VWIC provides clocking to the AIM, which provides it to the digital T1/E1 packet voice trunk network module (that is, to the PBX).

•The digital T1/E1 packet voice trunk network module provides clocking to the AIM, which provides it to the multiflex trunk VWIC.

•The ATM network and the PBX run their own clocks, which are not necessarily synchronized. However, this scenario could result in poor voice quality.

For a detailed discussion of clock sources on individual ports, see "Clock Sources on Digital T1/E1 Voice Ports" section in the "Configuring Voice Ports" chapter in the Cisco IOS Voice, Video, and Fax Configuration Guide, Release 12.2.

---

Note You must configure the controller for PRI or DS0 groups and for ATM AIM or CAS before configuring network clock participate parameters.

---

To configure network clock timing and priority for ATM and digital voice ports on the specified platform, complete these steps.

To configure the AIM-ATM-VOICE-30 card for high-complexity codecs and time slot, use the following commands.

SUMMARY STEPS

1. enable

2. configure terminal

3. voice-card slot-value

4. codec complexity {high | medium}

5. dspfarm

6. exit

7. controller e1 slot/port

8. ds0-group 0 timeslot 1-16

9. exit

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables higher privilege levels, such as privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	voice-card slot-value Example: Router(config)# voice-card 0	Enters voice-card configuration mode to configure DSP resources on the specified card. •The slot value is the AIM slot number on the router chassis: –Cisco 2600 series and Cites 2600XM—0 –Cisco 3660—7 is AIM slot 0, and 8 is AIM slot 1 –Cisco 3725—3 is AIM slot 0, and 4 is AIM slot 1 –Cisco 3745—5 is AIM slot 0, and 6 is AIM slot 1
Step 4	codec complexity {high | medium} Example: Router(voice-card)# codec complexity high	Changes the codec complexity to high or medium and matches the DSP complexity packaging to the supported codecs. •Using the high keyword changes codec complexity to high. Using the medium keyword changes the codec complexity configuration back to medium (the default complexity). •When the codec complexity configuration changes, the system prompts you to remove all existing DS0 or PRI groups using the following voice cards: –0 (Cisco 2600 series and Cisco 2600XM) –7 or 8 (Cisco 3660). –3 or 4 (Cisco 3725) –5 or 6 (Cisco 3745) Then all DSPs are reset, loaded with the specified firmware image, and released. Note For switched calls, you can configure a high-complexity codec even when the DSPs are loaded with medium-complexity firmware. However, an error message is displayed on the console during the call setup when a high-complexity codec is detected. •This command affects all the DSPs on this voice card. You cannot specify the DSP firmware type based on the DSP chip type.
Step 5	dspfarm Example: Router(config-voicecard)# dspfarm	(Optional) Enters the DSP resources on the AIM specified in the voice-card command into the DSP resource pool.

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable Example: Router> enable	Enables higher privilege levels, such as privileged EXEC mode. •Enter your password if prompted.
Step 2	configure terminal Example: Router# configure terminal	Enters global configuration mode.
Step 3	controller e1 slot/port Example: Router(config)# controller e1 0/1	Enters controller configuration mode on the E1 controller on the selected slot and port. •In this example, a VWIC E1 card is installed in WIC slot 0.
Step 4	clock source {line [primary] | internal} Example: Router(config-controller)# clock source internal	Specifies the source from which the phase-locked loop (PLL) on this port derives its clocking, and if the source is from the line or whether this port is the primary source. The default is line. •The primary keyword specifies that the PLL on this port derives its clocking from the external source to which the port is connected. This option also puts a second port, which is generally connected to the private branch exchange (PBX), into looped-time mode. Both ports are configured with line, but only the port connected to the external source is configured with primary. •The internal keyword specifies that the clock is generated from the T1 or E1 controller internal PLL. Note If you accept the default, the clock source configuration does not appear in the show running-config command output. Use the show controller command to display the current clock source for a port.
Step 5	channel-group channel-group-number timeslots timeslot-range [speed bit-rate] aim aim-slot-number Example: Router(config-controller)# channel-group 1 timeslots 1-5 aim 0	Directs HDLC traffic from the T1/E1 interface to the AIM-ATM-VOICE-30 digital signaling processor (DSP) card.
Step 6	ds0-group ds0-group-number timeslots timeslot-list type e&m-immediate-start Example: Router(config-controller)# ds0-group 2 timeslots 6-12 type e&m-immediate-start	Adds DS0 groups on the T1/E1 controller and configures high-complexity time slots. Note If you are adding PRI groups instead of DS0 groups, skip this step and proceed to Step 7. •The ds0-group-number argument specifies the DS0 time slots that make up a logical voice port on a T1 or E1 controller. •The timeslots timeslot-list keyword and argument signify a single time-slot number, a single range of numbers, or multiple ranges of numbers separated by commas. –For T1, allowable values are from 1 to 24. –For E1, allowable values are from 1 to 31 •When running high-complexity codecs with the AIM-ATM-VOICE-30 module, up to 16 voice channels can be processed. •The type keyword specifies the signaling type by which the router communicates with the PBX or public switched telephone network (PSTN). •The signaling method selection for the type keyword depends on the connection that you are making. The recEive and transMit or ear and mouth (E&M) interface allows connection for PBX trunk lines (tie lines) and telephone equipment. The e&m-immediate-start keyword is one of the type keyword choices and is listed on the ds0-group command reference page in the Cisco IOS Voice, Video, and Fax Command Reference, Release 12.2 T.
Step 7	pri-group timeslots timeslot-range | d-channel timeslot | rlm-timeslot timeslot number] Example: Router(config-controller)# pri-group timeslots 6-23	Adds PRI groups on the T1/E1 controller. •The timeslots timeslot-range keyword and argument represent a single range of values. T1 range is from 1 to 23. E1 range is from 1 to 15. Note Only one PRI group can be configured on a controller.
Step 8	exit Example: Router(config-controller)# exit	Exits controller configuration mode and completes the process for configuring serial data WAN.
