Configuring T1 and E1 Interfaces

Configuring Codec Complexity

The number of channels that an HDV network module can support depends on the number of PVDMs

that are installed and the complexity level of the codecs (vocoders) needed to support the required

compression method. The HDV network module supports the following number of channels:

• Up to 6 channels per PVDM (up to 30 channels for cards with 5 PVDMs installed) for high

complexity codecs (vocoders) that support the following services: G.711, G.726, G.729, G.723.1,

G.728, and fax relay

• Up to 12 channels per PVDM (up to 60 channels for cards with 5 PVDMs installed) for medium

complexity codecs (vocoders) that support the following services: G.711, G.726, G.729a, and fax

relay

Each HDV network module can support only one type of compression complexity (either high or

medium), although HDV network modules with different compression complexity types can be installed

in the same router.

Use the following procedure to configure the codec (vocoder) complexity on your HDV network module.

Step 2

Router(config-controller)# exit

Exit controller configuration mode.

Step 3

Router(config)# connect id controller-1

tdm-group-no-1 controller-2 tdm-group-no-2

Configure cross-connect pass-through between

two controllers.

Command Purpose

Step 1

Router> enable

Password: password

Router#

Enter enable mode. Enter the password.

You have entered enable mode when the prompt

changes to

Router#.

Step 2

Router# configure terminal

Enter configuration commands, one per line.

End with CNTL/Z.

Router(config)#

Enter global configuration mode. You have

entered global configuration mode when the

prompt changes to

Router(config)#.

Step 3

Router(config)# voice-card {0-4}

Select the voice card to configure.

Step 4

Router(config-voicecard)# codec complexity

{high |medium}

Specify the compression complexity for the voice

card.One complexity type is allowed per router.

Step 5

Router(config-voicecard)# exit

Exit back to global configuration mode.

Return to Step 3 if your router has more than one

voice card that you need to configure.

Step 6

Router(config)# Ctrl-z

When you finish configuring interfaces, return to

enable mode.
