Would this be useful in a voice lab?

Would the EM ports be useful? I already have a 2610 with 4-port ISDN cards, but not sure if that will be useful either. Anyway, please look at the description of the router and let me know if this would be useful in a voice lab.

I did try to get a 3660 on eBay.... but finally decided it was overkill for a home lab (plus it finally sold for over $800

)

I didn't have a PBX laying around, so I skipped the E&M interface. From a previous post:

An Ear and Mouth (E&M) interface supports tie-line facilities or signals between telephone switches. You can use the E&M voice interface card (VIC) to integrate VoIP with the legacy voice solution. The E&M VIC connects the Cisco router to a PBX.

So what kind of ports would be most appropriate? FXS/FXO ports?

Hey... I just had an urge to collect some of the "old posts" into a CCVP FAQ like in the CCNA forum! But then I got over it

It would make it easier to find the old posts I'm looking for -- but luckly I "cross-linked" some of the hardware posts, so if I find one, I can find the other(s).

I had the 2 NM-V2s with the VIC-2FXS and VIX-2FXO modules and the VG200 with the VIC-2FXS and VIX-2FXO modules. And I finally got 2 MC3810s for a great price (populated, not the overpriced empty shells some people sell on eBay).

I plugged the FXO into my outside line or the POTs Simulator/Ascend Max 6000. I used the FXS for regular analog phones and FAX machines (my fax/scanner/printers and laptop with fax modem).

Check out the Analog Signaling (E & M, DID, FXS, FXO) web page for a quick 2 paragraph blurb -- and a bunch of links you will learn to love or hate. Highlights follow:

A Foreign Exchange Station (FXS) interface connects directly to a standard telephone, fax machine, or similar device and supplies ring, voltage, and dial tone.

The Cisco Foreign Exchange Office (FXO) interface is an RJ-11 connector that allows an analog connection to be directed at the public switched telephone network's (PSTN's) central office or to a station interface on a private branch exchange (PBX).
