PA-FCHA

Fusion Call Contro l 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 Hi gh Le v el Data Link Co ntrolle r (HDLC) f ormat, then dr ops and in serts (D/ I) onto a partic ular channel
(or channels) of the ITU-T G.703 digital interface.
