Introduction
About The ShoreGear T1/E1 Voice Switches
Each ShoreGear T1/E1 Voice Switch connects internal extensions or IP phones to a
central ofce (CO) digital trunk line.
The switch provides connectivity through:
• Two RJ-45 LAN connectors
• One RJ-45 Telco port for connecting the switch to a telephone company line
• One RJ-45 Monitor port for connecting test equipment
• One DB-9 (female), RS-232C maintenance port (19200 bps, 8 bits, no parity, 1 stop
bit, no handshake) for serial communications
• One audio input port (3.5 mm stereo) for connecting to a music-on-hold source
• One audio output port (3.5 mm stereo) for connecting to a corporate paging system
or night bell
The ShoreGear T1/E1 Voice Switch package contains:
• ShoreGear T1 / E1 Voice Switch (SG-220T1, SG-T1k, SG-220E1, or SG-E1k)
• Power cord
• Stick-on feet for surface installation
• Mounting Ears - attachable installation brackets
Installation Connections
Mounting the ShoreGear Voice Switch on a Flat Surface
If you plan to mount the switch on a at surface, rst attach the provided rubber feet
to the bottom corners of the device. (You can stack up to three switches in a surface
installation.)
Installing an SG-T1/E1 Switch in a 19-inch Rack
An SG-T1/E1 switch is placed in a 19-inch rack only by mounting a ShoreGear Dual Tray
into the rack, then installing the SG-T1/E1 into the Tray. You can install an SG-T1/E1
switch on the left or right side of the tray.
Refer to the Quick Install Guide for the ShoreGear Dual Tray for Tray installation
instructions and information on using the tray.
Installation Location Requirements
To ensure optimum operating conditions for the SG-T1/E1 voice switch, verify the
operating environment is adequately ventilated, free of gas or airborne particles, and
isolated from electrical noise.
Installation Equipment
To install the switch, you need the following equipment:
• AC surge protector for the power connection
• RJ-45 cables for connecting the switch to the local area network and telco lines
• Music-on-hold source with a standard mini-headphone Y-adapter (optional)
• #1 Phillips screwdriver
After setting up the network connections and conguring the SG-T1/
E1 Voice Switch for operations, you can connect your T1 (SG-220T1
or SG-T1k) or E1 (SG-220E1 or SG-E1k) line to the switch.
Use an RJ-45 T1 cable to connect your T1 or E1 line to the Telco port.
For detailed information on switch port and trunk conguration, see the
sections “Conguring Switches” and “Conguring Trunks” in the Shore-
Tel Administration Guide.
Connecting a T1 or E1 Line
Powering on the ShoreGear Voice Switch
After connecting the switch to the network, power on the device by connecting it to an
AC power source.
1. Plug an AC surge protector (not provided) into a grounded AC power source.
2. Plug one end of the provided power cord into the receptacle on the back of the
switch, then plug the other end into the AC surge protector.
The power LED ashes momentarily, and remains lit.
• If the LED is not lit, make sure the power cord is plugged into the switch and the
power source.
• If the LED continues ashing, there is an internal error. Unplug the switch to power
it off, then power it back on. Refer to the “Conguring Switches” chapter in the
ShoreTel Administration Guide for information on ash patterns, or contact the
ShoreTel Support Services at http://www.shoretel.com.
The LAN ports auto-sense the network transport rate. When the network connection is
established, the network LED indicates a transport rate of 10 Mbps or 100 Mbps, and
whether the switch is receiving and transmitting data.

Once the SG-T1/E1 Voice Switch is secured to a rack or surface-
mounted, you can connect it to the data network.
Use an RJ-45 Ethernet cable to connect one or both of the LAN
ports to the network subnet.
While both ports can detect and respond to link status, the switch
uses only one LAN port at a time.
Connecting the ShoreGear Voice Switch to the Network
Optional Connections
After connecting the voice switch to the LAN, you can make optional
connections, including input from a music-on-hold source or output
to your internal paging system.
1. Connect a music-on-hold source (CD player or other audio
source) to the audio input port.
2. Connect your site’s paging system to the audio output port.
German: Das ShoreGear Voice-Schaltgerät auf einer ebenen
Oberäche montieren
Wenn Sie planen, das Gerät auf einer ebenen Oberäche zu montieren, befestigen Sie
zunächst die mitgelieferten Gummifüße an den unteren Ecken des Geräts. (Bei einer
Oberächeninstallation können Sie bis zu drei Schaltgeräte übereinander stapeln.)
Servicing Procedures
WARNING: SG-T1/E1 switches contain no internal eld serviceable parts. Return the
equipment to ShoreTel for any required service procedures.
CAUTION: Internal fuses should be serviced only by qualied ShoreTel personnel. If
internal fuses are blown and require replacement, return the SG-T1/E1 switch to ShoreTel
for service.
WARTUNGSVERFAHREN
ACHTUNG: SG-T1/E1 enthält keine internen Teile, die vor Ort gewartet werden können.
Senden Sie das Gerät an ShoreTel, falls Wartungsarbeiten erforderlich sein sollten.
VORSICHT: Interne Sicherungen dürfen nur von qualizierten ShoreTel-Mitarbeitern
gewartet werden. Wenn interne Sicherungen ausgetauscht werden müssen, senden Sie

Power LED
The power LED indicates the operating status of the switch.
Light Description
Steady The switch is powered on, and the internal software is running.

Yellow Flashing-Fast At least one port is handling an active call and at least one port is out of
service.
Network Conguration
Once the ShoreGear voice switch is installed and powered on, it must be congured for
network operations. A voice switch gets a network conguration by assignment from a
DHCP or BOOTP server, or directly from an administrator console (see procedure below).
For more information on setting up a switch for automatic conguration by a DHCP or
BOOTP server, see the ShoreTel Planning and Installation Guide.
Conguring the Voice Switch from a Console
1. Use a straight-through serial cable, DB9 male to DB9 female, to connect the switch to a
console PC.
2. On the PC or laptop, start a terminal emulation program and connect to the voice switch
using these serial communication settings: 19200 bps, 8 data bits, no parity, one stop bit, no
handshake.
3. At the login prompt, enter:
Login: anonymous
Password: ShoreTel
4. Choose Menu Options and follow the onscreen instructions for setting network parameters,
including IP address, subnet mask, and gateway.
