3.4.2 Central Office Incoming Call (Ring Down)
Each node can specify a terminating node for Ring Down calls using the system data. In this example,
Node A and Node D specify Node C and Node E as the terminating node respectively. The terminating
node is assigned using the ASYDL command (SYS 1,  Index 640). Note that self-FPC is assigned at the
terminating node.
Note 1:When assigning the data regarding the call...

3.4.3 Day/Night Change
Day/Night information is transferred from an ATTCON/DESKCON to predetermined nodes.  In this example,
Node C specifies Node A and Node B as destination nodes by assigning FPCs 1 and 2 in Indexes 704-735. Node
A and Node B specifies Node C as a terminating node for Ring Down calls from PSTN by assigning FPC 3 in
Index 640. Node E specifies Node D as a destination.

2.2 PA-FCHA (FCH)
Set the switches on the FCH (PA-FCHA) card(s) as shown below. This card has DIP switches, whose key
settings determine the time slots of the Fusion link. In Figure 4-5, CH3 is designated as the D/I channel in
an example.

Note 1:
64Kbps is used for T1 or E1 interface.
56Kbps is used for T1 interface with bit stealing.
48Kbps is used for T1 interface with both bit stealing and Zero Code Suppression (or Bit 7 Stuffing).
Note 2:When n is bigger than 1, Time Slot Sequence Integrity (TSSI) must be guaranteed at the network side.
Note 3:The following is an example key setting when n = 2.
