Multifrequency Signaling
Multifrequency (MF) signaling is a form of address signaling used between 
switches and the central office (CO). It is similar to dual-tone multifrequency 
(DTMF) signaling in that tones convey the dialed number.
With MF signaling, the signal is typically a combination of two frequencies from 
a group of 5 or 6 frequencies (2/5 or...

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:
nPublic 2/5
nPublic 2/6
nIbercom 2/5
nIbercom 2/6
MF Shuttle
MF shuttle signaling, for country code 15 (Russia), uses R1 frequency and 
noncompelled signaling. With MF shuttle signaling, it is...

nIf DEFINITY ECS makes an outgoing call to the CO that uses an open 
numbering plan, the CO should send the signal A.1 to DEFINITY ECS 
after sending the last address digit to the CO. Then, the CO should timeout 
and send a pulsed signal A.3 to DEFINITY ECS requesting the Group II 
signal.
Guidelines for administering MF signaling

Second, you assign the correlation between signal codes and their meanings.
1. Assign a code to every message. The code consists of a group category, like 
group II or A, and a number.
nFor example, you might assign code A.1 to the message 
“next-digit.” 
2. Assign a signal to each identifying code. 
nIn every country, the frequencies (levels may differ by...

nAuthorization Codes
The COR of the authorization code as administered on the 
authorization-code form is not used for ANI prefix determination, even if 
the originating endpoint enters an authorization code before call processing 
for an outgoing call seizes an outgoing trunk. If the originating endpoint is 
an extension, the extension’s ANI is used. If the...

nHunt Groups and Automatic Call Distribution (ACD) Splits
For ANI, a physical terminal’s extension number and COR overrides the 
extension number and COR of the hunt group or ACD split that the 
terminal is a member of or logged into. ANI prefix and ANI truncation 
apply to terminals that are members of hunt groups or logged into ACD 
splits.

For India Only. If ANI digits are padded with “zero,” then zeroes also are 
displayed along with ANI digits.
nTandem / Offnet Calls
If ANI digits are received on incoming MFC calls, the ANI digits are sent 
to outgoing tandem/off-net calls.
For Russia Only. The ANI is requested on incoming trunks only when all 
the address digits have been collected. When the incoming...

Trunk Answer from Any Station
Trunk Answer from Any Station (TAAS) allows phone users to answer all 
incoming calls to the attendant when the attendant is not on duty and when other 
phones have not been designated to answer the calls. The incoming call activates a 
gong, bell, or chime and a phone user dials an access code to answer the call.
Users can activate TAAS if...
