Unframed Operation - Paradyne HOTWIRE 7924 User Manual

When the V.35 payload rate is set for less than 1536 Kbps, that payload rate
determines which T1 DS0s are used, as follows:

Unframed Operation

Some earlier units do not support unframed operation when connected to a
V.35-compatible unit. To determine whether or not your DSX-1 nest card
termination unit supports unframed operation when connected to a
V.35-compatible unit, all three of the following conditions must be true:

1. The DSX-1 nest card termination unit must have a firmware revision number
of 7 or higher.
The firmware revision number is the last two digits on the first line of the label
located on the nest card EPROM located at U5. Refer to
Chapter 3, for the location of the EPROM.
