Integral X.21/V.11 Data Channel
Technical Overview
The Sprint 2
LANLink
X.21/V.11 data channel provides a single synchronous data interface
to complement the standard seven V.24 channels.
The data channel may be set to the following bit rates 1200bps, 2400bps, 4800bps, 8000bps,
9600bps, 19.2Kbps, 32Kbps, 38.4Kbps or 48Kbps.
Configuration Procedure
The internal X.21/V.11 channel is configured from the standard terminal display. Display
options are listed below.
