6.1.1
In an ISDN system the digital line card connects subscribers to the PCM highway as well
as to each other. The optimum controlling device for such a line card is the Extended
Line Card Interface Controller (ELIC) PEB 20550. Integrating the PCM interface
controller EPIC, two independent HDLC controllers SACCO-A and SACCO-B, and a D-
channel arbiter onto a single chip, the ELIC offers a high degree of specialisation, while
maintaining wide-ranging flexibility.
Figure 123
Digital PBX
This Application Note demonstrates operation of the ELIC as the key device of the digital
PBX shown in figure 123, by establishing a connection from subscriber A to subscriber
B. In this application the Configurable Interface (CFI) of the EPIC is set to IOM-2 (LC)
protocol, and thus the D-channel arbiter is used to link the SACCO-A to the CFI.
In particular this Application Note will show:
– how to initialize the ELIC CFI and PCM interface
– how to initialize SACCO-A and D-channel Arbiter to handle D-channel data
– how to initialize the SACCO-B to communicate via the PCM highway
– how to initialize the ELIC Control Memory to handle, monitor, control, and B-channels
– how to use the ELIC C/I channel to control the OCTAT-P
– how to use the SACCO-A for D-channel communication with subscribers
– how to switch a telephone connection between subscribers A and B.
As a starting position this Application Note assumes that ELIC and OCTAT-P have been
reset.
