Cables, Connectors, and Pinouts
Three G.703 serial interface cables are available for use with the PA-2CE1; two cables for balanced
120-ohm 2CE1 interface connections, and one cable for an unbalanced 75-ohm 2CE1 interface
connection.
Note
The PA-2CE1 leave the factory configured for balanced 120-ohm or unbalanced 75-ohm
connections. Depending on the circumstances, you might need to change the configuration
of both PA-2CE1 interfaces. See the “Setting the PA-2CE1 Jumpers” section on page 3-8
for instructions that explain how to change the configuration of both PA-2CE1 interfaces.
All three cables have a 15-pin, D-shell (DB-15) connector at the router (VIP2 or Cisco 7200 series) end
and either twin axial, RJ-45, or BNC connectors at the network end. Figure 1-4, Figure 1-5, and
Figure 1-6 show the 2CE1 interface cables.
Following are the product numbers for the 2CE1 interface cables:
•
Twin axial cable—CAB-E1-TWINAX(=) or equivalent
•
RJ-45 cable—CAB-E1-PRI(=) or equivalent
•
BNC cable—CAB-E1-BNC(=) or equivalent
