Cabling The Mcc1 Media Gateways-Center Stage Switch; Connecting Fiber Optic Cables - Avaya S8700 Installation Instructions Manual

Cabling the MCC1 Media Gateways—center
stage switch
This section provides connectivity information for MCC1 Media Gateways using a center stage switch
(CSS) to connect four or more port networks (PNs).
Signals between the PN with the CSS (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 CSS 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:
Make the required connections for the installation:
•

Connecting fiber optic cables

•
Connecting duplex- or high-reliability center stage switch-connected PN1 with one switch node
on page 124
•
Connecting critical reliability CSS-connected PN1 with one switch node
Connecting fiber optic cables
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 one 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.
3
Route the fiber optic cables from the transceiver out of the media gateway. Secure the cables to
the cable-tie rack. Keep the fiber optic cables clear of the heavier I/O cables.
4
If the media gateway in the TO column in the running list is located remotely from the FROM
media gateway, connect to the TO media gateway by way of the LIU.
Installing the Avaya S8700 Media Server with an Avaya G650 Media Gateway

The PN with the CSS contains Class 1 LASER devices. Prolonged eye contact with active
unterminated fiber optic cables may cause damage to the eyes.

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.
