The VoIPDB, required for IP telephones to communicate with non-VoIP
UNIVERGE SV8100 telephones, and to place or receive outside calls,
must be connected to either an external switching hub or to the Router
blade.
The blade plugs into a universal slot and does not consume any port.
Each blade provides eight RJ-45 port connectors. These are used to
connect to LAN terminals. Depending on the type of LAN terminal, the
blade may not detect the difference between straight cable and crossover
cable automatically. If auto-crossover is not functioning, use straight cable
for that terminal connection.
Table 4-53 CD-RTB Maximum Upgrade Capacities provides the
maximum capacities for the CD-RTB blades when they are upgraded.

The Router blade can provide also power over category 5 network cables.
This eliminates installing separate power adapters for each IP telephone
and allows for centralized power backup.
