configuration, such as the type of electrical interface of the port, which may be different on

the local side from the remote side. On the other hand, most channel parameters, for

example, channel rate, apply to both local and remote ports.

After choosing a local or remote context, the operator then chooses the channel number to

which subsequent commands will be directed. Once this selection is made the command

menu options, 1 through 12 are presented and the commands will only apply to that channel.

The following subsections outline each of the command menus comprising the Channel

Configuration.

4.7.3.1 Channel State [1]

This menu allows setting a selected channel in an operational mode, or either of two offline

states.

Option [1] - Un-Suspend Channel (also used to activate MANUAL restoral channels)

This option returns a suspended channel to active service with it‟s previously defined

configuration on the composite link to which it was allocated.

Option [2] - Allocate Channel on Composite Link A

Option [3] - Allocate Channel on Composite Link B

Option [4] - Suspend Channel

This option deactivates a channel and removes it‟s allocation from the composite link to

which it was assigned. However the channel parameters are saved so that the channel can

be un-suspended.

Option [5] - Take Channel Out Of Service

This option removes a channel from service along with any parameters assigned to it.
