Quad DS1 ADPCM Card
Card Configuration
Basic Setup
Before configuring the DS1 ADPCM card, there are some basics that need to be
considered:
l All DS0s to be compressed reside on T1 number 1 of the ADPCM card
l ADPCM is capable of transporting any combination of 64 and 32K
l All 24 DS0s can be transported either compressed or uncompressed, but not both
at the same time.
l All DS0s to be compressed must be set to type data.
The following is a basic setup:
Command Description
Connect T1 cable to port 1 of the ADPCM service card
set {adpcm_card-addr}
{none|map1|map2|map3}
Enable compressing by selecting Map type.
Note: none disables compression. See the
following section on Maps.
show (adpcm_card-addr} Displays the status of the card, and the mapping.
set {2:1:1-12} type data Set the channel (DS0) type to data on the
ADPCM channels. See set (ds0) command for
more information.
set {2:4:1-12} type data Set the channel (DS0) type to data on the
channels for cross-connect. See set (ds0)
command for more information.
connect 2:1:1-12 2:4:1-12 Set cross-connects.
The example connects all 24 channels of the
ADPCM to the 12 channels of the T1 (now
compressed) on port 4. Example is with map2
show connect adpcm {2:1) Displays the connections made above.
