Configuring The S2 Ip Address Parameter - Avaya 1000 Installation And Commissioning Manual

How the Branch Office feature works
• If the MG 1000B LTSP becomes unavailable, MG 1000B IP Phones registered to the main
office LTPS (in Normal Mode) are unaffected. MG 1000B IP Phones that are rebooted try to
register using S1, or S2 if programmed.
• If the MG 1000B TPS is unavailable, IP Phones at the main office or Branch Office have no
access to TDM resources (digital and analog telephones or PSTN trunks) at the Branch Office,
whether the IP Phones are registered using S1 or S2.
• Bandwidth management zones, emergency access, and time of day continue to work normally,
regardless of whether an IP Phone is registered using S1 or S2.
• If the CP PM at the Branch Office is initialized or rebooted, MG 1000B IP Phones can register
using S1 or S2. In this case, an administrator must manually redirect the S2-registered IP
Phones to register using S1 again.
• MG 1000B IP Phones registered to the main office using S2 are not redirected to the MG
1000B TPS during IP Phone firmware upgrade at the main office. MG 1000B IP Phones
registered using S2 receive firmware upgrades in the same manner as main office IP Phones.
The first time the MG 1000B IP Phone reboots after the firmware upgrade, it is directed to the
MG 1000B TPS using S1. Any different firmware is applied at that time, before the IP Phone is
redirected back to the main office TPS.
• MG 1000B IP Phones registered using S1 are redirected back to the MG 1000B Signaling
Server for any firmware upgrades, as described in
• MG 1000B IP Phones registered using S2 do not display "Test Local Mode."

Configuring the S2 IP Address parameter

For detailed information on configuring IP Phones, refer to Avaya IP Phones Fundamentals,
NN43001-368. This section contains a brief summary.
To configure the S2 parameter, do the following:
1. Reboot the MG 1000B IP Phone.
2. When the "Avaya" banner displays, quickly press the four keys under the display in
sequence, from left to right.
3. Program the IP address, subnet mask, and gateway addresses for the MG 1000B IP Phone.
4. Program the S1 IP Address, action, and retry parameters. The S1 IP Address is the MG
1000B Node IP Address.
5. Program the S2 IP Address, action, and retry parameters. The S2 IP Address is the main
office Node IP Address.
6. Program the remaining parameters. The IP Phone reboots again.
If the MG 1000B IP Phone can register with the main office using S1, it is redirected to the main
office TPS and operates as a normal Branch User.
