BCC
Generalized Route Selection uses the BCC to select the appropriate facilities for
routing voice and data calls. Far-end tandem switches also use the BCC to select
outgoing routing facilities with equivalent BCC classes.The entry in the Bearer
Capability Class field is used to select the appropriate facilities for incoming
ISDN calls. Avaya MultiVantage compares the entry in the BCC field to the value
of the Bearer Capability information element for the incoming call and routes the
call over appropriate facilities. For example, a call with BCC 4 will only be
connected through facilities that support 64 kbps data transmission.
The Bearer Capability Class field appears when all of the following are true:
■ Either the ISDN-BRI Trunks field or the ISDN-PRI field on the System
Parameters Customer-Options screen is
y.
■ The Group Type field is access, co, fx, tandem, tie, or wats.
■ The Comm Type field is data, avd, or rbavd.
Bit Rate
This field specifies the baud rate to be used by pooled modems. This field appears
when the Comm Type field is
avd or rbavd. It also appears if the Comm Type
field is
data, but only if the ISDN-PRI field is y on the System-Parameters
Customer-Options screen.
