8.5 The Interconnect Link
PORT CONFIGURATION FOR THE INTERCONNECT LINK
The Interconnect Link is for connection to another
Multiserver. From the Port Configuration Menu,
select option 3.
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).
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.

NSTALL 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).
