Special multipoint cables link the terminals together. Each cable has three connectors. The
first connector attaches to that terminal's interface. The second connector is a female multi-
point connector that attaches to the next terminal in the group. The third connector varies
depending upon the type of cable. In a First Multipoint Interface cable, the connector is a
male R8-232-C connector
that attaches to the modem. In the Daisy Chain Multipoint Interface
cable, the connector is a male multipoint connector that attaches to the multipoint interface of
the preceding terminal in the group.
When using synchronous modems, constructing a daisy chain requires the following cables:
• 132428:
First Multipoint Sychronous without Receive Clock (option 311)
• 13242Q: Daisy Chain Multipoint Synchronous (option 309)
