With T1 CAS E&M Feature Group B (FGB) from the telco and on the router/gateway, this feature group does not support ANI delivery to the PSTN. ANI (autmotic number identifier) is provided by the PSTN to the
To correct this issue and have the number changed on this T1 E&M "FGB" circuit, you must do 1 of 3
things to remedy:
1-Telephone company changes the ANI to the corrected number
2-(or) upgrade this long distance circuit to T1 PRI
3-(or) change the T1 CAS E&M feature group to "FGD" or better known as or "Feature Group D" and
reconfigure the router to support "FGD".
Here is the explanation of what "FGD" provides for you:
On Cisco implementation, signaling type "E&M-FGD" is taking the role of carrier.
For those who need to send ANI for outgoing calls using FGD, Cisco implemented FGD-EANA for this
purpose, which use TWO winks methodology.
EANA is a one stage dialing that contains two fields. The field transmitted first contains the call
customer?s identification number (ANI) that is used for billing purposes. Only MF pulsing is used
for ANI field.
The second field contains the called telephone number (DNIS). Either MF or DTMF pulsing can be used
for this field. When DTMF is used, there is no DNIS out-pulsed from BOC point of view, DNIS is
collected via voice band. The two fields are identified by special delimiter Key Pulse "KP" and
Start "ST", two special MF tones. When router received both ANI and DNIS (in MF mode), it sends out
a wink acknowledgment to BOC and from that point on the call is considered established.
When you say "Cisco is taking the role of carrier", what does that mean? Is it comparable to master/slave in PRI between Router/CO? If so, does it mean, I have to tell my Provider that I need to be "carrier"?
You say EANA provides ANI/DNIS for outgoing calls, does it also receive both? I found the following document, under "Restrictions" it says, EANA does not provide incoming ANI?
The router is sending ANI out to the carrier to forward rather than ANI originating at the carrier to forward.
My wording could have been more clear.
There is no need to inform the telco that you are acting as the carrier. That was my wording saying that your sending ANI, but, simply inform the telco that you want to enable FGD and that you will be forwarding ANI.
