CISCO ONS 15305 MULTISERVICE PROVISIONING PLATFORM FOR
SDH ACCESS NETWORKS
SDH ACCESS NETWORKS
The Cisco
®
ONS 15305 Multiservice Provisioning Platform (MSPP) is a small (one rack unit) solution that allows service
providers to collect high-capacity Ethernet and TDM traffic for transport over SDH networks. The product is typically
used for high-bandwidth service delivery to medium-sized and large businesses, and for traffic aggregation at small
central offices.
PRODUCT OVERVIEW
The Cisco ONS 15305 transports Ethernet and TDM traffic inside an SDH frame for metropolitan-area network (MAN or metro) applications.
The Cisco ONS 15305 can be used as customer premises equipment (CPE) for medium- and large-sized businesses - collecting voice and data
traffic from each site for switched voiced and data services, Layer 1 and Layer 2 VPNs, and Internet access - for transport over an STM-1,
STM-4, or STM-16 SDH uplink to the central office. The Cisco ONS 15305 can also be deployed as a central office aggregator; consolidating
STM-1 access links from Cisco ONS 15302 Multiservice Provisioning Platforms or other Cisco ONS 15305 CPE, as well as directly connected
customer TDM or data traffic from electrical interfaces.
The Cisco ONS 15305 can be deployed in many configurations: as an add/drop multiplexer, as a terminal multiplexer, as an STM-4/STM-16
cross-connect (non-blocking 64x64 STM-1 matrix at the VC-4/3/12 levels), and as a customer-access device. The system supports subnetwork
connection protection (SNCP) (VC-4/3/12) as well as 1+1 MSP
protection schemes. Ethernet connections over the SDH infrastructure can be
point-to-point or multipoint. The Cisco ONS 15305 can be configured with up to four plug-in service modules which may vary depending on
which application will be implemented.

The Cisco ONS 15305 management solution is based on an embedded Simple Network Management Protocol (SNMP) agent. A local craft
interface called Cisco Edge Craft and the element management system - Cisco Transport Manager - allow remote supervision and operation of
Cisco ONS 15305 devices. For scalability purposes, and to manage larger networks as a whole, Cisco Transport Manager offers a single-seat
management solution to operate networks with the Cisco ONS 15305 and all other Cisco optical products. The Cisco ONS 15305 also provides
a simple VT100 command-line interface (CLI) for initial configuration of the unit. Remote access is possible via IP Point-to-Point Protocol
(PPP)-based data communications network (DCN) or in band via one of the LAN or WAN ports.
