Cisco Compatible CAB-E1-PRI
E1- ISDN PRI Cable, 10 Feet
Product Highlights
Deploying or maintaining E1 ISDN PRI circuits on Cisco routing platforms requires the right interface cable — and a missing or damaged cable can mean costly downtime on critical voice and data links.
The CAB-E1-PRI is a Cisco compatible 10-foot (3-meter) E1 ISDN PRI network cable that connects Cisco routers and access servers to E1 Primary Rate Interface services. It features a DB-15 male connector on the Cisco equipment end and an RJ-45 male connector on the network termination end, with a copper conductor for dependable signal quality.
This cable is designed as a direct replacement for the original Cisco CAB-E1-PRI (also referenced as 72-1225-01) and is compatible with a wide range of Cisco platforms including the 7500 series, 7000 series, 4000 series, 3600 series routers, and Cisco access server systems such as the AS5200. Whether you are provisioning new E1 PRI trunks for voice gateways, replacing aging cabling in a telecom environment, or stocking spares for rapid fault resolution, the CAB-E1-PRI delivers the connectivity you need at a fraction of OEM cost.
Features & Benefits
E1 ISDN PRI Interface
Purpose-built for E1 Primary Rate Interface connections, this cable supports high-speed digital voice and data transmission over PRI circuits. It provides the physical link between your Cisco router's channelized E1 port and the carrier's network termination equipment.
DB-15 to RJ-45 Connector Pairing
The cable features a 15-pin DB-15 male connector on the Cisco equipment side and an RJ-45 male connector on the network side. This purpose-built pairing ensures correct pin mapping for E1 PRI signaling without the need for adapters or custom wiring.
Copper Conductor Construction
Built with copper conductors, the CAB-E1-PRI delivers reliable signal integrity and minimizes electromagnetic interference. This ensures consistent, low-error-rate performance on your PRI circuits.
Broad Cisco Platform Compatibility
Compatible with Cisco 7500, 7000, 4000, and 3600 series routers as well as Cisco access server systems. This wide compatibility makes it a versatile spare to keep on hand across multi-generation Cisco environments.
Deployment Scenarios
Voice Gateway PRI Trunk Connectivity
Connect a Cisco voice gateway router to an E1 PRI circuit from your telco provider. The CAB-E1-PRI links the router's channelized E1 interface module to the carrier demarcation point, enabling digital voice trunk services for PBX or unified communications deployments.
Access Server ISDN PRI Links
Provision ISDN PRI connections on Cisco access servers such as the AS5200 for dial-in or dial-out services. The cable provides the physical layer connection between the access server's E1 port and the ISDN network termination.
Spare / Replacement Cabling
Keep the CAB-E1-PRI on hand as a pre-tested spare for rapid fault resolution. When a cable failure takes down a PRI trunk, having a compatible replacement ready eliminates extended downtime and emergency procurement delays.
