NetVanta Octal T1/E1 Wide Module (P/N 1202843E1)
The NetVanta Octal T1/E1 Wide Module second generation (shown in
) provides eight T1 or E1
interfaces with RJ-45 wire connections. These interfaces can be used independently or as aggregate
bandwidth using Multilink PPP Protocol (MLPPP).

A DIP switch on the circuit board selects either T1 or E1 operation. All eight ports are
either T1 or E1. The default is T1. Refer to
either T1 or E1. The default is T1. Refer to

information.
A different service provider can be used on each interface. Each interface has an
independent clock.
