Fusion Call Control Handler
1. General Function
This circuit card is a protocol converter to carry the fusion-link-data from/to the other node. The Fusion-
Link-Data is received/transferred from/to the CPR via HUB (PA-M96) across the TCP/IP interface. Once
the FCH has received the fusion-link-data from the CPR, the HDLC CONT part of the FCH converts it to
the High Level Data Link Controller (HDLC) format, then drops...

Note:
The following operations are required prior to extracting the card.
(1.)  Turn on the MNT3 switch.
(2.)  Flip the MB switch.
When the D/I DTI (1.5M) is connected with the card front cable.
Note:T203 timer designates the maximum idle time which does not transmit any data frames. As a basic rule, the
shorter T203 timer value, the earlier link failure detection will be obtained.

When “n” is bigger than 1, the Time Slot Sequence Integrity (TSSI) must be guaranteed at the network.
When “n” is one or more, the corresponding D channels as “n” must be designated by SW11-SW12.
