SS7 Signaling

[Javier Concha]

Cisco 2851-CCME/K9 w/ VWIC2-1MF-T1-E1 supports S7 Signaling ?. I need to connect a ip network to PSTN. Thanks in advance.

There are 3 ways you can connect an ip network (CME) to PSTN

1. ISDN ( T1 PRI / EI PRI )

2. FXO ( analog)

3. SIP ( sip trunk - ip )

module type will be

VWIC2-1MFT-T1/E1= for T1 / ISDN

VIC2-2FXO= /  VIC2-4FXO=  for FXO

Thanks U.

Pls, what about E1?.  The public company in my city offer only E1 ss7, not R2 u other digital service
