Network Initiated DCLB
Possible Settings: Disable, V.54
Default Setting: V.54
Allows the initiation and termination of the Data Channel Loopback (DCLB V.54 Loop 2)
to be controlled by the receipt of a DCLB-actuate or DCLB-release sequence (either
V.54 or FT1-ANSI compliant) from the network on the B-channels used for the network
frame relay link. When enabled and a DCLB-activate sequence is received, the unit
initiates a DCLB on the network interface. When a DCLB-release sequence is received,
the DCLB is stopped.
Disable – DCLB-actuate and DCLB-release sequences are ignored.
V.54 – DCLB-actuate and DCLB-release sequences that comply with either V.54 or
ANSI T1.403, Annex B standard will be recognized and will control initiation and
termination of a DCLB for the network frame relay link. The actuate and release
sequences do not need to match (for example, a DCLB started with a V.54 actuate
sequence can be stopped with an FT1 release sequence).
Operating Rate (Kbps)
Possible Settings: Autorate, 64, 128
Default Setting: Autorate
Specifies the line rate, or automatic detection of the line rate, on the leased line BRI S/T
network interface.
Autorate – The rate is automatically detected by the unit by attempting to bring up the
frame relay LMI on one or both channels.
64 or 128 – Specifies the network operating rate to either 64 kbps or 128 kbps;
automatic rate detection is disabled.
