Cisco ONS 15310-MA SDH Multiservice Platform
The Cisco
®
ONS 15310-MA is a Multiservice Provisioning Platform (MSPP) that switches packet and TDM
traffic, and interfaces to both circuit-based and Ethernet/MPLS backbone networks. Together with the
Cisco ONS 15305, Cisco ONS 15454, and Cisco ONS 15600, the Cisco ONS 15310-MA provides an end-
to-end solution for multiservice transport over SDH networks.
Product Overview
The Cisco ONS 15310-MA (Figure 1) is a carrier-class MSPP that efficiently switches Ethernet and TDM traffic for
use in metropolitan and regional optical networks. Its flexibility and scalability allow it to support 2-Mbps to 2.5-Gbps
TDM, as well as 10/100/1000-Mbps Ethernet interfaces. The Cisco ONS 15310-MA can aggregate traffic at a central
office or collect services at the customer premises. At a central office, it can groom traffic from multiple customer-
located network elements, such as the Cisco ONS 15305, Cisco Catalyst
®
3750 Series Switch, or another Cisco
ONS 15310-MA for distribution to other networks or handoff to specialized networking devices, such as a ONS
15454 SDH, ONS 15454 MSPP-on-a-blade, ONS 15600 SDH, Cisco 7600 Series Router, a high-capacity digital
cross-connect (DXC), or a Class 5 telephone switch. At the customer premises, the Cisco ONS 15310-MA can
collect high-density and high-capacity traffic from medium-sized and large businesses, or from several customers in
a multitenant location.

Carrier-Class Compact MSPP
In a very compact chassis (six rack units [RUs]), the Cisco ONS 15310-MA provides six slots for hot-swappable
traffic interfaces. High-density electrical (up to 126 E1), Ethernet (up to 32 10/100BASE-T and up to 24 GE), or
optical interfaces can be terminated in this small footprint to optimize use of expensive real estate at the central
office or remote terminal cabinet. A centralized two-stage 20-Gbps AU-4 and 5-Gbps TU12-TDM cross-connect can
switch SDH encapsulated traffic from any tributary port onto any optical interface.
All Cisco ONS 15310-MA common equipment, including processor, cross-connect, timing, and power supply, can be
optionally duplicated for 99.999% reliability. Protection for TDM electrical as well as optical interfaces is also
possible. Subnewtork Connection Protection (SNCP) and Multiplex Section Protection 1+1 (MSP) can be configured
for greater fault tolerance in the optical network. The Cisco ONS 15310-MA is CE compliant, and supports industrial
