Cable a 3-cabinet G600 system
The procedure to connect the TDM-/LAN-bus cable for three cabinets is essentially the same as
described in the previous section, Cable a 2-cabinet G600 system
on page 80.
For three cabinets (A, B, and C), mount Cabinet A at the bottom, Cabinet B in the middle above A, and
Cabinet C at the top above B. Between A and B, connect the TDM-/LAN-bus cable to the right pin field
on both cabinets. Between B and C, connect the TDM-bus cable to the left pin field on both cabinets. The
TDM-/LAN-bus terminators are installed on the left pin field on Cabinet A and on the right pin field on
Cabinet C.
Install G600 patch panels and external modem
NOTE:
The optional patch-panel kit replaces standard 110A cross-connect hardware. If standard
110A cross-connect equipment is used, consult DEFINITY Communications System
Generic 1 and Generic 3 Main Distribution Field Design (555-230-630).
Patch panels are arrays of RJ45 jacks and associated B25A cabling to accommodate 2-wire, 24-port
DCP/analog port boards and 8-port analog trunk boards.
A shelf is provided to serve as a mounting surface for the external modem and other optional equipment.
The shelf can also be used to secure the B25A cables.
Install patch panels and shelf
Refer to Figure 17, Typical G600’s patch-panel and modem installation, on page 85 while performing this
procedure.
1 Using the supplied mounting screws, mount the patch panels on the rack below processor cabinet.
2 Using the supplied mounting screws, mount the shelf on the rack below the patch panels.
3 Attach B25A cables to the patch panels and the circuit packs’ amphenol connectors.
NOTE:
Connect 24-port DCP/Analog circuit packs to the 24-port patch panels.
NOTE:
Connect 8-port Analog Trunk, “combo,” or DID Trunk circuit packs to either of the first
two banks on the 8-port patch panel. If an 8-port BRI Trunk circuit pack (TN2185B) is
present, connect it to the 3
rd
bank on the 8-port patch panel.
NOTE:
The patch panels do not have to be mounted in the same rack as the cabinet. They can be
mounted in phone closets as appropriate.
