Multifrequency signaling
Issue 5 October 2002 1773555-233-506
R2-MFC is a version of MFC recommended by the International
Telecommunication Union (ITU). It provides signaling between a CO and a
switch over analog or digital CO, DID, or DIOD trunks. It also provides signaling
between 2 MultiVantage switches.
Avaya MultiVantage provides MF signaling that complies with ITU regulations
and national regulations for specific countries. It provides these types of MF
signaling: MFE) MF Shuttle, and multifrequency compelled (R2-MFC). These
protocols signal the called number, the calling party’s number (ANI), and
information about the type of call or type of caller (category).
Avaya MultiVantage allows prefix digits for ANI sent on outgoing calls to be
defined per PBX or per the originator’s class of restriction.
If a call is a tandem call and the incoming and outgoing trunk use different
protocols, the switch makes no attempt to convert between the various protocol’s
meanings for category. Instead,
■ the PBX uses the incoming trunk’s COR assigned category if the outgoing
trunk is Russian or R2-MFC, and
■ the PBX uses ARS call types if the outgoing trunk is MFE.
Avaya MultiVantage provides the incoming ANI to all features on the switch that
need to identify the calling party.
MFE
MFE, for Country code 11 (Spain), uses R1 frequency and compelled signaling. It
is available on CO and DID trunk groups. There are four kinds of MFE signaling:
■ Public 2/5
■ Public 2/6
■ Ibercom 2/5
■ Ibercom 2/6
MF Shuttle
MF shuttle signaling, for country code 15 (Russia), uses R1 frequency and
noncompelled signaling. With MF shuttle signaling, it is possible to change to
decadic rotary pulse in the middle of address signal exchange. MF shuttle
signaling is available on CO, DID, and DIOD trunk groups.
Also, ANI transmission, for Country code 15, uses a gapless R1 MF signal and is
completed within 800ms. This is available on an outgoing CO trunk group.
