T7630 Dual T1/E1 5.0 V Short-Haul Terminator (Terminator-II)
Features
The T7630 Dual T1/E1 Terminator consists of two
independent, highly integrated, software-config-
urable, full-featured short-haul transceiver/framers.
The T7630 provides glueless interconnection from a
T1/E1 line to a digital PCM system. Minimal external
clocks are needed. Only a system clock/frame sync
and a phase-locked line rate clock are required. Sys-
tem diagnostic and performance monitoring capabil-
ity with integrated programmable test pattern
generator/detector and loopback modes is provided.

4-state, and 16-state; D4 2-state and 4-state;
SLC-96 2-state, 4-state, 9-state and 16-state. E1
signaling modes: transparent and CAS.
I
Alarm reporting and performance monitoring per
AT&T, ANSI*, and ITU-T standards.
I
Programmable, independent transmit and receive
system interfaces at a 2.048 MHz, 4.096 MHz, or
8.192 MHz data rate.
I
System interface master mode for generation of
system frame sync from the line source.
I

for generation of system clock from the line source.
Facility Data Link Features
I
HDLC or transparent modes.
I
Automatic transmission and detection of ANSI
T1.403 FDL performance report message and bit-
oriented codes.
I
64-byte FIFO in both transmit and receive direc-
tions.
Microprocessor Interface
I
33 MHz, 8-bit data interface, no wait-states.
I
Intel
or Motorola
interface modes with multi-
plexed or demultiplexed buses.
I
Directly addressable control registers.
Applications
I
