What kind of gateway I can use ?

[imt000040]

Good day to you.

Can you help me to find a gateway for 20 analog

in/outbound lines that form SS7(PSTN Service Provider) ?

Because we won't application for PRI Trunk .

Currently, we use a lagecy PBX as a gateway function

for convert analog to PRI. (Connection with Cat.6509

T1 voice blade)

We want to resale the lagecy PBX .

The Cisco VG-200 http://www.cisco.com/univercd/cc/td/doc/pcat/vg200.htm might work well for you.

The VG200 can't handle 20 analog loop start telephone lines.

Right now there are no gateways that have a high density of FXO ports (which is the style of port that you need to connect to an analog PSTN line) so the most you could get on a single card is 4. So you would need 5 NM-2V modules, each with a pair of VIC-2FXO style cards, and the only box that will hold that many all in a single chassis is a 3660 series router. Or if you prefer you can purchase 5 VG200 gateways and put 4 ports in each one.
