Configuring Codec Complexity - Cisco 2620 Configuration Manual

Chapter 3 Configuring with the Command-Line Interface
To configure TDM connect, complete the following steps in controller configuration mode:
Command
Step 1 To configure a TDM channel group for T1:
a
Router(config-controller)# tdm-group
tdm-group-no timeslot timeslot-list [type
{e&m | fxs [loop-start | ground-start] |
fxo [loop-start | ground-start]}]
To configure a TDM channel gorup for E1:
b
Router(config-controller)# tdm-group
tdm-group-no timeslot timeslot-list [type
{e&m | fxs [loop-start | ground-start] |
fxo [loop-start | ground-start] |
fxs-melcas | fxo-melcas | e&m-melcas}]
Step 2
Router(config-controller)# exit
Step 3
Router(config)# connect id controller-1
tdm-group-no-1 controller-2 tdm-group-no-2

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:
•
•
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.
OL-1957-04
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

Configuring T1 and E1 Interfaces
Purpose
Configure a TDM channel group for T1. If
configuring cross-connect for data traffic only, do
not specify the type option. The type option only
applies if the mode cas command is enabled.
Configure a TDM channel group for E1. The
"melcas" options are supported only on E1 and
apply to the Mercury Exchange Limited (MEL)
Channel Associated Signaling (CAS) standard,
used primarily in the United Kingdom. The MEL
options help preserve CAS integrity on the line. If
configuring cross-connect for data traffic only, do
not specify the type option. The type option only
applies if the mode cas command is enabled.
Exit controller configuration mode.
Configure cross-connect pass-through between
two controllers.
