The DC Power Supply Module specification is described as follows: 

•

Input topology: 
Four-terminal DC input power connector for each Power Supply Module. 

•

Connector type: 
Screw barrier connectors. 

•

Input voltage: 
-38 to -75 VDC (nominal -48 to -60 VDC) 

•

Maximum input current: 
7.0 Amps 

Note: maximum input current is measured at the lowest input voltage that the power supply continues 

to operate. This is not the same as used for determining agency input current markings. 

•

Input power: 
200 Watts, fully equipped 

The AC Power Supply Module specification is described as follows: 

•

Input topology: 
AC input power connectors for AC-input Power Supply Cage. The lower AC connector connects to the 

right hand Power Supply Module as viewed from the rear. The upper AC connector connects to the left 

hand Power Supply Module as viewed from the rear. 

Note: A second Power Supply Module is a customer installed option. 

•

Connector type: 
IEC 320 mains input connector. 

•

Input voltage: 
Auto-ranging for either:
100 to 127 VAC 
200 to 240 VAC 

•

Frequency range: 
50/60 Hz

•

Maximum continuous input current: 
2.5 Amps @ 100 to 127 VAC 
1.2 Amps @ 200 to 240 VAC 

•

Input power: 
230 Watts, fully equipped 

The signaling link specification is described as follows:

•

Signaling links: 
The number of signaling links depends on the product variant, which determines the type and number of 

SS7 Signaling Boards included. See 

 for more information.

•

Source: 
PCM (T1/E1) interface 

SS7 (V.11) serial interface (for SS7G21 only). 

•

Data rate: 
48 kbit/s, 56 kbit/s and 64 kbit/s. 

•

Timeslot: 
Fully programmable.
