Model Number: G703-FTEC-AC
S/N: E1103V01103100630002
Brand: CTC Union
Made in Taiwan
This is the Manufacturer Product Description from theInternet:
The G.703-FTEC is a T1/E1 converter and timeslot crossconnect which enables conversion between one T1 signal and one E1 signal. Testsand 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&TTR-62411 standards, and supports both D4 or ESF frame formats with B8ZS or AMIline code. The E1 interface complies with ITU G.703, G.704, G.732, and G.823standards, and supports both 2 and 16 frames per multiframe without CRC-4 andframing with CRC-4. The line code is HDB3.
All setup controls are performed via internal DIP switchsettings.
