NetVanta Octal T1/E1 Wide Module (P/N 1202843E1/L1)
The NetVanta Octal T1/E1 Wide Module second generation (shown in Figure 9) provides eight T1 or E1
interfaces with RJ-48C wire connections. These interfaces can be used independently or as aggregate
bandwidth using multi-link PPP protocol. Table A-4 on page 50 and Table A-5 on page 50 give the pinouts
for this module.
