How Do I Configure VISM-PR Cards?
6.9.4.6 Configuring TDM Signaling for CAS on VISM-PR
To configure time-division multiplexing signaling for CAS, complete the following steps:
Step 1 Add a CAS variant to the VISM-PR card—See 6.9.4.6.1 Adding a CAS Variant to a VISM-PR Card,
page 6-180.
Step 2 Configure the CAS variant and timing parameters—See 6.9.4.6.2 Configuring the CAS Variant and
Timing Parameters, page 6-182.
Step 3 Associate an endpoint with the CAS variant—See 6.9.4.6.3 Associating an Endpoint With a CAS
Variant, page 6-183.
6.9.4.6.1 Adding a CAS Variant to a VISM-PR Card
Step 1 From the Domain Explorer window, choose Configuration > MGX 8880/8850 MG > Configuration
Center.
Step 2 Under the Elements tab, within the node, double-click the VISM-PR card.
Step 3 Click the CAS tab. The CAS Parameters category is selected by default.
Step 4 Click Create. The Create CAS Parameters window appears.
CAS Outgoing MGCP
Package
Controls (in conjunction with the card level persistentXgcpEventsTable) how
persistent CAS events (like answer, disconnect, etc.) related to an outgoing
call observed on this DS0 are notified to the MGC.
Music Threshold Music on hold threshold in dBm.
Sid Package Specifies whether the Silence Indication Detection packet should be generated
when silence suppression is in active mode.
DSP Channel Level
RAS
Status of DSP channel level RAS on the VISM-PR. When it is enabled,
VISM-PR will configure the DSP through a HOST-DSP message on the
individual channel.
Companding Law Indicates whether input from or output to the TDM side of DS0 is u-law or
a-law stream. Setting of this object does not take effect unless the
corresponding DSP channel is closed and re-opened.
