How many calls 3661 Voice gateway can handle? help

hi,

i have 3661 with E&M connecting the PBX,

if my PBX Supports 120 phones, it means the 3661

can handle 120 calls concurrently?

if i used 3661 with 6 NM-2V (12 VIC-2FXS),it can

handle 24 calls concurrently?

if i used AS5300 WITH 4E1(can support 120 calls ),connect to the PBX,if the PBX supports 200 calls, does it mean the AS5300 support 200 calls concurrently?

thank you

Re: How many calls 3661 Voice gateway can handle? help

The gateway can support the number of possible voice channels, not necessarily the number of phones on the PBX. With 6 NM-2V, you can support 24 calls (since that is 4 calls/ports per NM-2V). The NM-2V will support E&M or FXS or FXO. With Digital ports on the 3661, you can support many more calls simultaneous since each T1/E1 will support 24/30 calls.

With the AS5300 you have 4 E1. This means 4X30 = 120 calls. If PBX supports 200 calls, you still are limited by the number of voice channels you can connect to the AS5300 which is 120.

Re: How many calls 3661 Voice gateway can handle? help

what's the Digital ports on the 3661, for example:

with 3661 i have NM-HDV-1E1-60=, the diagram i supposed is below:

(60)ip phone ----switch----3661(NM-HDV-1E1-60=)---WAN

or

60 phone---PBX---3661(NM-HDV-1E1-60=)----WAN,

which one is correct?

if the last one is correct, which cable for 3661 connecting PBX,

THANK YOU IN ADVANCE
