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
Pls, what about E1?. The public company in my city offer only E1 ss7, not R2 u other digital service
this card is for T1 / E1
