Cisco 15310-28WBE-3BBE 28-Port DS1 and 3-Port DS3E/EC-1 1531028WBE3BBE

Description:

The Cisco 15310-28WBE-3BBE Interface Module is a telecommunications network module designed for Cisco ONS 15310 optical transport platforms to provide integrated DS1 and DS3/EC-1 connectivity. Featuring twenty-eight DS1 ports and three DS3/EC-1 ports, this module enables efficient aggregation and transport of TDM services across optical networks. Network engineers, system integrators, and telecommunications maintenance teams use this module for network upgrades, infrastructure expansion, service aggregation, and replacement of existing interface modules in carrier and enterprise optical transport systems.

Applications:

The Cisco 15310-28WBE-3BBE module is widely used in telecommunications and optical transport networks where DS1 and DS3 circuits must be aggregated and transmitted across SONET infrastructures. Typical deployments include service provider backbone networks, metropolitan transport networks, enterprise telecommunications infrastructure, and legacy TDM service delivery systems where reliable circuit transport and network scalability are required.
