V.25Bis Dialing; Field Values For Command Strings - Zhone IMACS 8000 User Manual

HSU Card
Once a Master Dialing command is issued for HSU 821360 RS366 dialing ports, all further
dialing commands on this port will be applied to the new slot and port designated by the
Master Dialing command.
To return the RS366 to its normal position, the user can apply the special value of 0 (zero).
The command, *3500, tells the RS366 dialing to return to its home port. Table 14-18 shows
the possible modes of RS366 dialing, and command structures.

14.3.16 V.25bis Dialing

The 821360 HSU card also recognizes V.25bis commands, as in-band protocol for dialing by
DTE equipment. V.25bis defines two modes, Addressed and Direct. The Direct call mode is
enabled by selecting dtr as the dial trigger from the Dial Screen on the HSU card. The
Addressed call mode is enabled by selecting v.25b as the dial trigger. Reference to V.25bis will
be for the Addressed mode only. Refers to dtr dialing will be for the Direct mode and can be
found in the HSU section. This method allows the use of control signals and commands sent
over the HSU Card data interface to establish and terminate calls. Addressed calls are
packaged in synchronous data frames and are sent when the interface is idle.
CRN commands can alter existing call profiles loaded to the HSU card with new telephone
numbers and bandwidth without having to access the call profile through the HSu card screen.
CRS commands can load call profiles form the Interface card without having to use the Load
command form the HSU card screen.
New call profiles and changes made to existing call profiles are permanent and will remain
with the card until changed by any of the procedures discussed in this chapter.
