H.6 Racks and Cabling
H.6.1 General Cabling Overview
The diagram in Figure H-5 highlights the key components with respect to cabling for your
voice network.
Starting from the left in this diagram, the telephone cabling is organized as follows:
A telephone jack (RJ-11) is provided for each telephone.
Telephone cabling (Category 3 or better) is terminated on the telephone jack and
runs back to the equipment room to a modular connector (RJ-21X) on a telephone
patch panel.
The telephone patch panel provides a flexible cable management solution for the
telephone cabling. The patch panel has RJ-21X connections for the telephone
cabling and RJ-11 connections on the front.
Patch cords are connected from the telephone patch panel (RJ-11) to the voice
switch patch panel (RJ-11).
The voice switch patch panel provides a flexible cable management solution for the
voice switches. The patch panel has RJ-21X connections running to the voice
switches and RJ-11 connections on the front.
Starting from the right in Figure H-5, the trunk cabling is organized as follows:
The digital (T1) and analog trunks are terminated on a punch-down block.
The digital service is further terminated at a service provider demark with an RJ-48
connector.
An RJ-48 cable from the T1 demark connects to the ShoreGear-T1.
The analog service is cross-connected to a modular (RJ-21X) punch-down block.
A telco cable is connected to the modular (RJ-21X) punch-down jackand runs to a
modular connector (RJ-21X) on an analog trunk patch panel.
Like the telephone cabling, patch cords are connected from the analog trunk patch
panel (RJ-11) to the voice switch patch panel (RJ-11).
As an alternative, patch panels can be replaced with punch-down blocks. This may be more
cost-effective but is less flexible.
