Multifrequency Signaling 

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 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 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.

■

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.
