NetVanta Octal T1/E1 Wide Module (P/N 1202843E1)
The NetVanta Octal T1/E1 Wide Module second generation (shown in Figure 11) 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). Table A-6 on page 58 and Table A-7 on page 58 give
the pinouts for this module.

Features and Specifications
Operating Modes
• Frame Relay, Multilink Frame Relay
• PPP, Multilink PPP
• HDLC
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
T1/E1 Mode DIP Switch on page 31 for more
information.
