N+1 Configuration
The 7800 N+1 patch panels function as the bridge between the provider network and the TMG7800-
STM1 gateways. To properly wire your gateways to the 7800 N+1 patch panel(s) to provide N+1
protection, follow these guidelines.
1.
Prepare a diagram that links each Tmedia unit serial number with an N+1 patch panel port and the
network provider's STM1. This diagram will help for the web portal configuration later on.
2.
Relate the fiber optic cables from the network provider with each TMG7800-STM1 and use the
same port number that is assigned to each TMG7800-STM1. See
figure
4.9 on page

3.
If Automatic Protection Switching (APS) is used then repeat the EXACT SAME numbering scheme
for each APS connection. For example, if a TMG7800-STM1 is assigned port number one on a
7800 N+1 patch panel that is being used for main connections, then the APS connections must also
be assigned port number one on a 7800 N+1 patch panel that is being used for APS connections.
4.
Connect the 1 unit to the N+1 port of the N+1 patch panel.
