Chapter 7. Configuring the Voice Interfaces
DLCI Map
The options for DLCI MAP vary depending on the MODE and
HOST/REM selections.
Selections Available for a Unit in Direct Mode
For direct connections, the DLCI for voice traffic must be speci-
fied. This information must be specified in both the local and
remote units. Voice data may be multiplexed with data on the
same DLCI.
L1 DLCI
Local DLCI that Line 1 voice data is carried on.
L2 DLCI
Local DLCI that Line 2 voice data is carried on.
Selections Available for a Host Unit in Switched Mode
This selection gives access to the remote extension table that is
maintained by the host unit. The table consists of a local DLCI
associated with the voice data on a remote FSU 5622 ESP and the
extension for the two voice ports connected to that DLCI. The
FSU 5622 ESP supports up to 20 DLCIs which yield a total of 40
voice ports. The front panel Next, Previous, Add, and Delete
keys are used to edit this table. The DLCI/Extension informa-
tion is communicated to the remote units over the network so
configuration is not required on the remote units.
L1 Ext
Extension for Line 1 on a remote FSU 5622 ESP.
L2 Ext
Extension for Line 2 on a remote FSU 5622 ESP.
DLCI
Local DLCI that carries L1/L2 data.
Port
When cascading units, select the port (Network, DTE 1, DTE 2)
that the voice channel resides on.
