NetVanta E1/FE1 + G.703 Drop NIM (P/N 1200878E1/L1)
The NetVanta E1/FE1 + G.703 Drop NIM (see Figure 11) provides a single
WAN-E1
interface
(2.043 Mbps) with user-selectable TS0 assignment and a G.703 drop port which may be used to drop and
insert traffic to an E1 PBX. See Table A-5 on page 50 for the E1 pinouts. See Table A-7 on page 51 for the
G.703 pinouts. See Table A-7 on page 51 for the DBU connector pinouts. An optional DIM is required for
dial backup applications.
