DHCP on Nortel 1140E Phones

[mrclean613]

Greetings ~

Newbie here _ I'm trying to figure out how our 1140E phones register during a reboot. I'm new to this position - with no documentation from the install. We're preparing for a scheduled "failover test" at our campus. So I've been preparing documentation for test procedures along with technical document with all the Nortel SS IP Configurations.

Main office (HQ)        - We have a CS1000M - backup SS w/ backup NRS - all PSTN traverse Thu here
Admin-1 (A1)            - CS1000E - SS w/ primary NRS
Branch Office (BO)     - CS1000B w/pri to pstn
Remote office (RO)     - here's where we have 200 1140e phones homed to HQ

Looking to figure some things out here - been through Nortel on-line docs - just getting overloaded

Looking to keep it simple

Oh... another challenge - I see on the (RO) phones have no entry for S2 - so my question here is what happens during a loss of connection to S1?

Thanks for the guidance,

Hi mrclean613 and welcome to the forums!

Le me answer your question up front... given your description the IP phones at the remote office will likely up and die.

There are a number of ways to provide the S1, S2, S3 values (some times so many ways it can be confusing). You can use DHCP (Nortel-i2004A, Nortel-i2004B) and you can use the Info Block (TFTP, HTTP) provisioning. You can also static the information within the IP phones themselves.

When we setup a small remote office we generally use an SRG. The SRG serves two purposes, 1) provide dial-tone in the event of a WAN failure or disconnect from the Main Office CS1000 and 2) provide PSTN access for E-911 locationing. If you are working on a large remote office then you can step up to a CS1000B (Branch).

Good Luck!
