Chapter 3 Installing a Cisco 7200 VXR Router
Connecting I/O Controller, NPE-G1, or NPE-G2 Cables

require an RJ-45-to-DB-25 adapter, and possibly a DB-25-to-DB9 adapter. Refer to
Table 3-17 for the
cable and adapter configurations that can be used to connect terminals and modems to the Cisco 7200
VXR routers.
