ENTRY:

For most applications, select Sync External Clocks. This is used when connecting to another Multiserver across a link via a communications device (CSU/DSU module, external CSU/DSU, or external modem).

SET LINK RATE [SYNC EXTERNAL CLOCKS]:

1 Sync External Clocks

Options 2 through 11 are used if you are connecting the Multiservers back to back in close proximity (without a communication device such as a modem or CSU/DSU) or for providing clocking to a device (such as a channel bank). These instances are relatively rare.

Important

The Multiserver must be node-reset (to current configuration) after the link rate for the interconnect port has been set

Once the port has been configured for an interconnect link and reset, the CCM indicator for that port will begin to flash. It will continue to flash until the link has been correctly installed and is operational.

INSTALL THE INTERCONNECT LINK

Assuming that you have installed and configured the communications device for the interconnect link (either the CSU/DSU module, an external ISU, or an external modem), connect the interconnect cable. If the external devices are not RS-232, the appropriate converters or adapters are required. See Section 5.8, Converters, for installation instruction.

Appendix B: Cabling Diagrams has information on the cables you should use and their pin assignments.

You can verify the integrity of the link by observing that the CCM indicator light goes off for the port being used (A1, A2, or A3).
