Voice Switch Requirements Chapter H: ShoreGear IPBX Voice Switches
370
H.1.6.1 Power Cabling
Each ShoreGear voice switch comes equipped with a standard 110 VAC modular power
cord. A localized modular power cord can be ordered from ShoreTel. ShoreTel recommends
that every ShoreGear voice switch, as well as the ShoreWare server, be connected to an
uninterruptable power supply (UPS).
H.1.6.2 Ethernet Cabling
Each ShoreGear voice switch has an RJ-45 connector that provides an auto-sensing
10/100M Ethernet interface. This is connected to the local area network using standard
Category 5 cabling.
10 Base-T can typically support up to 150 meters, while 100 Base-T can support up to 100
meters.
H.1.6.3 IP Phone Cabling
Each ShorePhone IP phone has an RJ-45 connector that provides an auto-sensing
10/100M Ethernet interface. This is connected to the local area network using standard
Category 5 cabling.
10 Base-T can typically support up to 150 meters, while 100 Base-T can support up to 100
meters.
H.1.6.4 Analog Telephone and Trunk Cabling
The ShoreGear-24, ShoreGear-12, and ShoreGear-Teleworker, voice switches have RJ-11
connectors that provide telephone and trunk interfaces. These should be connected using
standard Category 3 twisted-wire cabling or better.
In addition, the ShoreGear-24 and ShoreGear-12 provide an RJ-21X male connector as an
alternative for mass termination of the telephones and trunks. This should be connected
using a standard 25-pair cable. ShoreTel recommends using the RJ-21X and connecting to a
patch panel to provide simple moves, adds, and changes.
Telephones can be supported from 0 to 2,000 feet from the voice switch over standard
cabling. Use larger gauge wires for longer distances. For example, with a ShoreGear-12 and
#22AWG wire, you can obtain loop lengths of over 6,000 feet.
It is recommended that an analog telephone be provisioned in the equipment room for
troubleshooting purposes.
The pinout of the ShoreGear-24 and ShoreGear-12 RJ-21X connectors are shown in the
section Section H.7 on page 378.
H.1.6.5 T1 Trunk and Trunk Monitor Cabling
The ShoreGear-T1 voice switches have an RJ-48C connector as the telco interface to the T1
trunk from the telephone service provider.
These voice switches provide an internal Channel Service Unit (CSU).
The ShoreGear-T1 have an additional RJ-48C connector that is wired to the telco interface
for the purpose of troubleshooting the T1 interface with specialized test equipment. This
connector is normally not used.
