R2-MFC
R2-MFC permits each country to define the meanings of the R2 frequency
combinations.
R2-MFC Considerations
■ Both non-group II signaling and group II signaling are supported on
incoming MF signaling calls. The group II signaling protocol has an extra
signal that provides caller-category information. Only group II signaling is
supported on outgoing MF signaling calls.
■ MF signaling also can be used in tandem trunk groups. After address
signals are collected from an incoming group II MF signaling call, the call
can route to a group II MF signaling trunk.
■ Both incoming and outgoing MF signaling calls support ANI. The terminal
displays ANI information and the CDR record records it.
■ When Avaya MultiVantage uses an open numbering plan, the end-of-dial
signal must be defined in the incoming Group I signal administration. After
sending all address digits, the CO sends the end-of-dial signal to Avaya
MultiVantage.
■ If Avaya MultiVantage makes an outgoing call to the CO that uses an open
numbering plan, the CO should send the signal A.1 to Avaya MultiVantage
after sending the last address digit to the CO. Then, the CO should time-out
and send a pulsed signal A.3 to Avaya MultiVantage requesting the Group
II signal.
■ Avaya MultiVantage offers the option to record the Calling Party Category
in the CDR. For incoming external calls, this comes from the Group II
signal. For internal calls and station-originated external calls, this comes
from the COR of the originating station. For tandem calls, this value comes
from the Group II signal, determined by the COR of the originating trunk
group. The CDR device must be capable of receiving this information. See
‘‘CDR System Parameters’’ on page 646 for more information.
■ You can assign Calling Party Category and Called Party Category on a
trunk-by-trunk basis. See ‘‘Multifrequency-Signaling-Related System
Parameters’’ on page 1045 for more information.
■ You can record and announcement to play when outgoing R2-MFC trunk
calls do not complete. This applies when Avaya MultiVantage receives
either group A or B signals from the called Central Office or other switch.
