Document: 10022
Category: 2890 T1 to Fiber Modem
Date Posted: 05/30/02 |
Problem
How far will the 2890 transmit on the electrical side? Also, does the 2890 generate a T1 signal for
loopback testing?
Solution
The 2890 (T1 over Fiber Bit-Driver) can transmit the following distances which are based on 22 AWG solid twisted
pair wire:

The 2890 does not generate a T1 signal. The T1 signal must originate from an external source.
