| Description |
Features
|
The G.703-FTEC is a T1/E1 converter and timeslot cross
connect which enables conversion between one T1 signal and one E1 signal. Tests
and diagnostics can easily be performed from the front panel push-switches.
Diagnostics include T1 local/ remote and E1 local/remote loop back.
The T1
interface complies with ANSI T1.403, and AT&T TR-62411 standards, and
supports both D4 or ESF frame formats with B8ZS or AMI line code. The E1
interface complies with ITU G.703, G.704, G.732, and G.823 standards, and
supports both 2 and 16 frames per multiframe without CRC-4 and framing with
CRC-4. The line code is HDB3.
All setup controls are performed via internal
DIP switch settings. |
Support G.802 Annex B
Enables equipment to operate
at T1 and E1 rates.
converts between T1 and E1
data and signaling.
Configurable A-law / µ-law
signaling conversion.
Transparent conversion at
64kbps timeslot level.
Controlled slip for buffer
over/underflow.
The 24 timeslots of T1(nx64)
can be inserted into E1(nx64), 30/CAS or 31/CCS timeslots.
Local/remote loopback test
capabilities on both T1 and E1 interface.
Complies with CCITT G.703,
G.704, G.823 recommendations.
Function setting via internal
DIP switch setting or Console Port.
