Features and technical reference
1439Multifrequency Signaling

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, automatic number identification (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.
R2-MFC
R2-MFC permits each country to define the meanings of the R2 frequency
combinations. Specific frequency combinations for different countries are
described in the DEFINITY ECS Application Notes for Type Approval.
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 Call Detail Recording (CDR) record
records it.
■ When DEFINITY ECS 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
DEFINITY ECS.
