CHAPTER 10: Switching Configuration

111

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.

XAMPLE 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.

• 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.

KEY: Channels paired and connected

Channels paired but not connected because Channel Types were unlike

Channel pairing attempted, but no port available in the “to” range
