NetVanta T1/FT1 NEBS NIM (P/N 1200862L2#NEBS)
The T1/FT1 NEBS NIM (see Figure 24) T1 WAN interface for the NetVanta 1224STR DC. The T1 NEBS NIM
is NEBS Level 3 compliant, and provides a full T1 or fractional T1 network interface. See Table A-6 on page 63
for the WAN-T1 connector pinouts.
Although the T1/FT1 NEBS NIM is compliant with NEBS Level 3, the NetVanta 1224STR
DC unit supports only NEBS Level 1.
