PA-PC94
Data Link Multiplexer
1. General Function
This circuit card mainly provides the two functions: 1) collection of BLF/TGBL information (associated
with Attendant/Desk Console operation) from DLKC cards of all nodes in an IPX-U/IPX-UMG system,
and 2) distribution of the collected data to ATI cards of all nodes. While a DLKC card can manage this pro-
cessing solely on an accommodated node basis, the use of this card makes possible the BLF/TGBL man-
agement even on a system basis, via the Inter-node Switch (ISW). Note that this card is mounted in a PIM
of any node, and if necessary, can have an optional dual configuration.
For details on BLF/TGBL information, refer to the following service features explained in the “Feature
Programming Manual”.
• Busy Lamp Field-Flexible [B-2]
• Trunk Group Busy Lamp [T-9]

Note:
IN - DLMX card gathers BLF/TGBL information from DLKC card of each node, via ISW/CMG.
OUT - DLMX card sends the collected BLF/TGBL information to ATI card(s) of each node, via ISW/
CMG.
This figure shows an example where a pair of DLMX cards (No. 0/No. 1 system) is accommodated in a PIM of
LN0/LMG0.
