Connecting Cables to SFP Modules
Warning
To comply with the Telcordia GR-1089 NEBS standard for electromagnetic compatibility and safety, connect
the Gigabit Ethernet ports only to intra-building or unexposed wiring or cable. The intrabuilding cable must
be shielded and the shield must be grounded at both ends. The intra-building port(s) of the equipment or
subassembly must not be metallically connected to interfaces that connect to the OSP or its wiring. These
interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as described in
GR-1089-CORE) and require isolation from the exposed OSP cabling. The addition of Primary Protectors is
not sufficient protection in order to connect these interfaces metallically to OSP wiring.
Note
When installing the cabling to the RSPs, we recommend that you leave a service loop of extra cabling sufficient
to allow for fan tray removal.
Follow these steps to connect the cable to a copper Gigabit Ethernet port:
Procedure
Step 1
Confirm that the router is powered off.
Step 2
Connect one end of the cable to the Gigabit Ethernet port on the router.
Step 3
Connect the other end to the BTS patch or demarcation panel at your site.

Connecting T1/E1 Cables
The physical layer interface for the Cisco ASR 907 Router T1/E1 port is a customer-installed high-density
connector. The high-density connector has thumbscrews which should be screwed into the interface when the
cable is installed.
Note
Patch panels are required in order to connect the high-density interface connectors to individual T1/E1 lines.
Installing the Cable Connectors
T1/E1 Cable Connectors
One end of the cable (see the figure above) has a 68-pin connector that plugs into the T1/E1 interface module
and the other end of the cable with a 68-pin connector is connected to a RJ48, AMP64 or a DIN patch panel.
Use the thumbscrews on either side of the connector to secure the cable to the interface.
