Install Generic 3 Management 
Terminal
This chapter contains Generic 3 Management Terminal (G3-MT) requirements. 
Also detailed is: 
nHow to directly connect a terminal to the switc h
nHow to set u p the terminal
nAlternative procedure to remotely connect a terminal to the switch. 
The Generic 3 Management Terminal (G3-MT) shipped with the system is a 715 
Management Terminal (715 MT). See the documentation p a cked with the 
terminal for information not contained in this chapter.
Generic 3 Management Terminal
(G3-MT) Requirements
One Generic 3 Management Terminal (G3-MT) should be located in the same 
equipment room as the cabinet or in sight of the cabinet and must b e within 50 
feet (18 meters) of the c a binet. It is strongly recommended the terminal be 
connected directly to the switch c a binet with the shortest possible cable. If 
desired, another terminal can be connected remotely.
!CAUTION:
When the terminal is being installed to support a DC-powered system or a 
system requiring electromagnetic shielding, a 116A Electronic Industries 
Association (EIA) ground isolator (comcode 106 005 242) must be installed 
at the back of the switch cabinet as shown in the schematic in Figure 6-2 
and as described in this chapter.

Mains p ower for the terminal must b e o btained from a standard volta ge source in 
the range of 115 to 230 volts AC in the equipment room. The terminal is 
auto-sensing and automatically adjusts to receive the typ e of AC power at the 
site.
An optional printer may b e used with the terminal to provide hard copies of 
administration data. A parallel printer should be connected to the printer or PAR 
port. A serial printer should b e connected to the Data Communication Equip ment 
(DCE) port.
Always c onnect the terminal cable to the Data Terminal Equipment (DTE) port on 
the back of the terminal. See  Table  6-1.
Figure Notes:

2. Data Communication Equipment (DCE) port to which optional serial printer is connected.
3. Dat a T erm i na l E q u i p m e nt (DTE )  p o rt to whi c h  c a b l e f rom  switch is always connected. No 
matter what the position of the Data Terminal Equipment (DTE) port, always connect the 
cable from the switch to the port.

2.If you have a DC-powered switch control cabinet or if you need 
electromagnetic shielding
, locate the 116A Electronic Industries 
Association (EIA) Ground Isolator (c omcode 106 005 242) and install it in 
the TERMINAL connector on the rear of the switch control cabinet (for 
standard reliability, und u plicate d systems); or in the DUPLICATION 
OPTION TERMINAL connector (for high and critical reliability, duplicated 
systems), and skip to Ste p 4 b elow. See Figure 6-3 for the position of 
these two connectors at the rear of the switch cabinet.
If you do not have a DC-powered switch control c a binet, go d irectly to 
Step 3 below.
3. Use an M25B Electronic Industries Association (EIA) shielded cord (cable 
code H600-426) or an e quivalent to connect between the terminal DTE 
connector and the TERMINAL connector (unduplicated systems) or the 
DUPLICATION OPTION TERMINAL (duplicated systems) on the rear of 
the switch control carrier and skip to Step 5 below. 
4.
For DC-powered cabinets or for electromagnetic shielding, use an M25B 
(Electronic In dustries Association) shielded cord (cable code H600-426) 
or an equivalent to connect between the terminal DTE port and a 116A 
Electronic Industries Association (EIA) ground isolator (comc o de 106 005 
242) mounted in the TERMINAL connector (unduplicated systems) or the 
DUPLICATION OPTION TERMINAL connector (duplicated systems) 
position on the rear of the control carrier.

Activate the System
This chapter contains procedures for activating the system and bringing the 
switch up to a non-alarm (no red lights) state. This chapter details:
nPowering up the switch
nInstalling translation flash-memory card
nPowering up AC-powered switch
nPowering up DC-powered switc h
nVerifying messages on management terminal
nLogging in to the system
nSetting required country options
nChanging craft password
nSetting date and time
nSetting system maintenance parameters
nSaving  translations
 After the system is activated, the telephones and other equipment need to be 
installed (see Chapter 9, Install and Wire Telephones and Other Equipment).  
The system is administered by adding the customer data to match the wiring, 
telephones, and other equipment (see the reference to the book at the end of 
Chapter 9, Install and Wire Telephones and Other Equipment). The  telephones 
and other equipment are teste d (see Chapter 10, Test Telephones and Other 
Equipment).
!CAUTION:
While performing these procedures, you may need to reseat circ uit packs. 
To prevent damage from static electricity, always wear an Electromagnetic

Power Up Switch
To power up the switch, do the following:
Install Translation Flash-Memory Card
1. Verify  the write switch on the white Translation Flash-Memory Card  
(Translation Card) shipped with the system is positioned so  the card can 
be written. The write switch is shown in the correct position in Figure 7-1.
2. Install the Translation Card in the TN777B network control circuit pack. 
Insert the card into the slot in the direction indicated by the arrow on the 
card’s label as shown in Figure 7-1.
Figure Notes:
1. Insert card in direction of arrow into the slot.
2. Slot on TN777B circuit pack
3. Write switch positioned correctly
