Connecting a Cable to the Output 10-Mhz or 1-PPS Interface
Procedure
Step 1
Connect one end of a shielded mini-coax cable to the Slave unit.
Step 2
Connect the other end of the shielded mini-coax cable to the 10-Mhz or 1-PPS port on the RSP of the Cisco
ASR 920 Router.
Connecting a Cable to the ToD Interface
Procedure
Step 1
Connect one end of a straight-through Ethernet cable to the GPS unit.
Step 2
Connect the other end of the straight-through Ethernet cable to the ToD or 1-PPS port on the RSP of the Cisco
ASR 920 Router.

Cisco ASR 920 Series Aggregation Services

Note
Connecting Ethernet Cables
The Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router interface modules support RJ-45
and Ethernet SFP ports. For instructions on how to connect cables to Ethernet SFP ports, see
the Connecting
Cables to SFP Modules
section.
The RJ-45 port supports standard straight-through and crossover Category 5 unshielded twisted-pair (UTP)
cables. Cisco does not supply Category 5 UTP cables; these cables are available commercially.
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.
Warning
Follow these steps to connect a 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.
