CHAPTER 8: Link Configuration

8.6 The Mux Link
PORT CONFIGURATION FOR THE MUX LINK
The mux link is for connecting the Multiserver to a
feeder mux. The mux link can either be a leased
line or a crossover cable to a locally-placed feeder
mux. From the Port Configuration Menu, select
option 4.
The next menu will appear:
Most applications require option 1, Sync External
Clocks. This is for connection of a feeder mux via a
sync modem.
Options 2 through 8 are for a direct back-to-back
application where the feeder mux is in close
proximity to the Multiserver and there is no
modem. Both the CommBox II and the Statplex
Multiplexor rely on external clocking. Speed
compatibility between the Multiserver and these
multiplexors is not an issue. The configuration of
the feeder-mux port will determine the line speed
between the units.
Options 9 through 11 are for connection to an
async modem. Voice/Fax is not supported over
async modems.
Important
The Multiserver must be node-reset (to
current configuration) after the link rate
for the feeder mux port has been set.
I
NSTALL THE MUX LINK
Assuming that you have installed and configured
the synchronous modem for the mux link, connect
the cable. If you are connecting a feeder mux
directly to a Multiserver, you will need a crossover
cable (EZ423-0015).
Appendix B: Cabling Diagrams has information on
the cables you should use and their pin
assignments.
Once the connection is established, the integrity of
the mux link is verified by observing that the CCM
indicator light goes off for the port being used.
Important
Feeder muxes must be reset after the
mux link is connected to the
Multiserver. This will initialize the mux
so that it can work with a Multiserver.
