Synchronous Connections, Ports

voice-voice, async-async, sync-sync connections will be made.

If the “from” range is greater than the “to” range, the unpaired from ports will not be connected.

EXAMPLE OF FORCE-CONNECTING A RANGE

In the example in Figure 10-3, a user will attempt to force-connect 15 ports on the NEWYORK node to ports on the DENVER node. Because the “from” range is greater than the “to” range, only 13 ports will be paired (essentially truncating the last 2 ports). Out of the 13 paired ports, 9 connections will be made.

“from” range	=	NEWYORK/A2-D2
		(15 ports)
“to” range	=	DENVER/2 (beginning at
		port A2)

Notice the following:

•Ports NEWYORK/B1 and B2 are paired but not connected to DENVER/B1 and B2 because they are not the same channel type.

•Port numbers NEWYORK/B3-B6 made successful connections to DENVER/C1-C4 because their channel types match, even though the port numbers are different.

CHAPTER 10: Switching Configuration

•Ports NEWYORK/D1 and D2 are not paired up at all, because the “from” range is greater than the “to” range.

NOTE: If an async port within a specified range is connected to the Command Facility (via $CMD), it will not be force-connected.

10.4 Synchronous Connections

Sync ports must be connected via force-connect (option 3 on the Switching Control Menu). The connection may be between the local Multiserver and the remote Multiserver or it may be within the local Multiserver. Sync connections cannot be made to a feeder mux.

Before proceeding, note the following:

•To change protocol, you must force-disconnect the channel.

•When force-connecting, be sure that the protocols match. (Do not attempt to change protocols on one side only.) Be sure to reset the unit after reconfiguration.

When the connection is complete, the Switching Control Menu will reappear on the screen. Continue this process until all sync connections have been made.
