I have some basic questions about deploying or upgrading WAN & PSTN links for business use. I'm 100% on TCP/IP and the general technologies (DSL/cable/PSTN/TDM), so this thread is completely about carrier information, and what a technical engineer has to know & be prepared for when out in the field...
1) a customer has an existing T1 voice circuit, and we're wanting to replace the current T1 termination box (Adtran) w/ a Cisco router. I've learned that you can't simply replace the existing box with a Cisco router and T1 card (as I was hoping) - it's not a simple "swap" the connection to the new box process. WHY?? Please explain why the carrier has to be involved in such replacements, and what information the engineer must know before deploying the new router.
2) same for a DSL business line. Recently, our company sent an engineer out w/ a Cisco ASA to replace an existing (Nortel?) appliance - the site had a DSL connection, and once the engineer was on-site, nothing worked. I'm ridiculously naive when it comes to "business" DSL connections - I'd figured that it was a "plug & play" solution (similar to consumer cable/DSL), where you could swap the device behind the DSL box and be done.
So - WHAT information should be scoped about a DSL router (from the carrier?) before going onsite?
Launching some guy out there – what does he have to know? Existing WAN (T1/whatever) circuit, or maybe some DSL (routers?) business?? We want to put some ASA’s in front of these DSL boxes – pass-through? - WHAT questions should be asked????
When transferring a TDM/IAD (WHATEVER) circuit from one box to another – does it require carrier scheduling /intervention?//
