Cabling The Mcc1 Media Gateways-Css; Connect Fiber Optic Cables - Avaya S8700 Installing

94 Installing the Avaya™ S8700 Media Server with Avaya™ MCC1 or SCC1 Media Gateway
Cabling the MCC1 Media Gateways—CSS
This section provides connectivity information for MCC1 Media Gateways using a center stage
switch to connect 4 or more port networks (PNs).
Signals between the PN with the center stage switch (for convenience called PN1) and the other
PNs are carried by fiber optic cables. Lightwave transceivers provide the required fiber optic
interface.
The fiber optic cables from the center stage switch route to a Lightguide Interconnect Unit
(LIU) or fiber optic shelf.
Use multimode fiber transceivers and multimode fiber optic cables between media gateways
unless single-mode fiber is required (distance restrictions). Use metallic cables between
carriers.
!
CAUTION:
The PN with the center stage switch may contain a Class 1 LASER device if a
single-mode fiber optic cable is connected to a remote port network.
Make the required connections for the installation:

Connect Fiber Optic Cables

NOTE:
Always use the Cable Running List that accompanies the media gateway when installing
fiber optic cables. The following procedure is a typical example of how to cable an MCC1
Media Gateway with CSS.
If the media gateways are close together, the signal may go through a single, directly connected
fiber optic cable. If the media gateways are far apart, it may be easier to connect the media
gateways through an LIU or fiber shelf.
For each fiber indicated in the fiber optic Cable Running List:
1 Install a lightwave transceiver on the media gateway connector at the position in the
FROM column in the running list.
2 Select a cable indicated by the CABLE CODE and LENGTH in the running list. Connect
1 of the fibers to each connector on the lightwave transceivers just installed. The fiber is
numbered 1 or 2. The connector on the transceiver is labeled TX or RX. Keep track of
which fiber connects to which transceiver connector. Label both ends of these cables.
