In the next week or so, we'll be turning up a new T1 Pri from Cox Cable in Omaha using a T100P (installed but not yet configured). While discussing the interface parameters with a very knowledgable Cox engineer, we decided on some of the basics including b8zs, esf, dchan=24, callerid, 5 digits of called number forwarded to *, and switchtype=national (NI2). They indicated their CO switch is a DMS500 that is compatible with several different switchtypes including 5ess, dms100, etc. * will clock sync from this pri.
This system also has a tdm04b (4-port fxo) installed and working, and is expected to remain after the t100p is implemented. Zttool can see both cards at the moment. Questions: 1. Is a switchtype=national (NI2) a reasonable choice, or are there other types that others have found to be more usable/stable with * in the US? 2. Since the current system has a working tdm04b defined as fxsks=1-4 in /etc/zaptel.conf, how will I know when implementing the t100p whether those b-channels should be 5-28 or 1-23? (eg, which card has channel 1? It almost appears that defining the span= first with bchan=1-23 and follow it with fxsks=25-28 (for the tdm04b), is about the only way to do that without creating ambiguity for the reader.) Is that a reasonable approach or assumption? 3. Other then zttool, what other methods have others found useful for diagnosing layer 1 & 2 type issues remotely during an initial pri install? (After ensuring layer 1/2 functionality, I'm assuming 'pri debug', etc, is most appropriate for diagnosing higher layer and dialplan issues.) 4. In very general terms, when passing incoming pri calls to a specific extensions.conf context, is using 'exten => s,1...' a reasonable way to handle inbound calls initially? (Is the 'called number' passed in EXTEN like it is with sip calls?) Any other tips/tricks for handling an initial pri installation?
