Site Cabling Guidelines
This section contains guidelines for wiring and cabling at your site. When preparing your site for network
connections to the Cisco 1000 Series Router, consider the type of cable required for each component, and the
cable limitations. Consider the distance limitations for signaling, EMI, and connector compatibility. Possible
cable types are fiber, thick or thin coaxial, foil twisted-pair, or unshielded twisted-pair cabling.
Also consider any additional interface equipment you need, such as transceivers, hubs, switches, channel
service units (CSUs), or data service units (DSUs).
Before you begin, read these important notes about cabling:
• The E1 interface on the Cisco 8-Port Channelized T1/E1 SPA interface uses RJ-48c receptacles for E1
(120-Ohm) cables with RJ-45 connectors. You can use all ports simultaneously. Each E1 connection
supports interfaces that meet the G.703 standards. The RJ-45 connection does not require an external
transceiver. The E1 ports are E1 interfaces that use 120-ohm shielded twisted-pair (STP) cables.
• Shielded cables must be used to connect to the DB-25 alarm connector on both the AC and DC power
supplies in order to comply with FCC/EN55022/CISPR22 Class A emissions requirements. For
information about the power supply DB-25 alarm connector and alarm LEDs, see the xref
“
How Cisco
ASR1000-RP Alarm Monitoring Works ” section on page 2-22 .
Shielded T1/E1 cables must be used to comply with FCC/EN55022/CISPR22 Class A emissions
requirements on the 8-port channelized T1/E1 SPA interface.
Warning
Before you install the Cisco 1000 Series Router, have all additional external equipment and cables on hand.
For ordering information, contact a customer service representative.
The extent of your network and the distances between network interface connections depend in part on the
following factors:
• Signal type
• Signal speed
• Transmission medium
The distance and rate limits referenced in the following sections are the IEEE-recommended maximum speeds
and distances for signaling purposes. Use this information as a guideline in planning your network connections
