3. OPTION MODULES
The NetVanta 3000 Series offers several option modules designed to meet a variety of networking
requirements. The option modules are of two types: plug-in Network Interface Modules (NIMs) and
plug-on Dial Backup Interface Modules (DIMs).
NIMs are cards which plug directly into the option module slot (labeled
SLOT x NET/DBU), located on the
rear of the base unit. These cards provide the following types of interfaces:
• NetVanta 56K/64K NIM (P/N 1200861L1) on page 22
• NetVanta T1/FT1 NIM (P/N 1200862L1) on page 23
• NetVanta T1/FT1+DSX-1 NIM (P/N 1200863L1) on page 25
• NetVanta Serial NIM (P/N 1200866L1) on page 27
• NetVanta SHDSL NIM (P/N 1200867L1) on page 29
• NetVanta E1/FE1 NIM (P/N 1200868L1) on page 30
• NetVanta E1/FE1 with G.703 Drop NIM (P/N 1200878L1) on page 31
DIMs are plug-on cards which plug directly on to the NIM prior to installation into the base unit. A DIM
must be plugged on to a NIM in order for the
DBU port on the NIM to be active. NetVanta 3000 Series
Routers support two DIMs:
• NetVanta Analog Modem DIM (P/N 1200864L1) on page 33
• NetVanta ISDN BRI DIM (P/N 1200865L1) on page 34
This section describes each module, providing individual card specifications and features. Refer to Pin
Assignments on page 47 for pinout information. Installing Dial Backup and Network Interface Modules on
page 41 provides information on card installation.
