4.4.5 Router Installation
NCB-IM routers are always used in pairs with one at each end of the telephone line. Consequently,
of each pair, one must be set to Originate communication and the other to Answer. This applies to
both dial-up and leased-line modes. Perform the installation and cable connections of the router
using the following procedure as a guideline.
Procedure
Step 1. Route your the Echelon network wires in conduit into the cabinet.
Step 2. Orient the router on the extended JNISCAB-5's top shelf
Step 3. Set the DIP switches as needed for your application:
• Eight router OPTION A DIP switches. You must press the Reset pin on the NCB-IM router
after making changes to the Switch settings.
• DIP Switch Settings for Dial-Up and Leased-Line 2 and 4-Wire\
Step 4. All telephone line connections are made to the line connector on the NCB-IM router.
