System Configuration and Operation Signaling and Companding (BCON)
3.16 Signaling and Companding (BCON)
User card ports may or may not have a signaling mode applied to them when assigned to a
time slot. Typically, analog voice cards (i.e., E&M, FXO, FXS) will have their analog
signaling information converted to digital signaling bits which are then inserted into the digital
bitstream. Data card circuits (i.e., HSU, SRU, etc.), on the other hand, do not require the
system to perform any signaling processing or conversion.
Unlike DS0s terminating on voice or data cards in the system that will have controlled
signaling parameters, circuits that "pass through" your system must have signaling assigned
to them by the user. This ensures that the WAN cards either maintain existing signaling
patterns as in T1-T1 circuits or change and convert them for circuits going from a T1 to an E1
environment.
In Figure 3-57, time slots 1-8 and 13-18 are connected to user cards and therefore will have
signaling automatically turned off or on by the system depending on the type of user ports that
are assigned to them. Of the pass-through connections on the other time slots, you can either
select signaling or no signaling depending the type of equipment or channel facility on which
it is ultimately terminated. For voice circuits, you would probably want to enable signaling,
and for data equipment, you would probably want to disable signaling (the default). Further,
this screen allows you to request that signaling conversion and/or companding conversion be
performed on pass-through circuits.
