Cisco ONS 15302 - a terminal multiplexer optical entry network

The Cisco ONS 15302 is a terminal multiplexer that extends the optical accessibility network for the client premises. With an STM-1 uplink to SDH optical networks, the Cisco ONS 15302 can collect voice and information visitors for switched services, Web accessibility, and VPNs. In only one rack unit (RU), the Cisco ONS 15302 brings together details and voice website traffic by transporting Ethernet and TDM channels inside an SDH STM-1 body. A Layer two change cloth allows native 10/100BASE-T Ethernet mapping into as much as 4 virtual container groups (VCG) for point-to-stage or stage-to-multipoint transport over the SDH network. VCG bandwidth can be configured in as very small as two-Mbps increments.

The Cisco ONS 15302 management resolution is in accordance to an embedded Primary Network Management Protocol (SNMP) agent. A regional craft interface referred to as Cisco Edge Craft as well as the ingredient administration plan, Cisco Transport Manager, make it possible for remote supervision and provisioning for Cisco ONS 15302 gadgets. The Cisco ONS 15302 also delivers a easy VT100 command-line interface (CLI) for initial set up and immediate administration from the device. Directors can handle the software by accessing it regionally by means of the VT100 RS-232 port or the dedicated Ethernet administration port. Remote entry is likely by way of IP Point-to-Level Protocol (PPP)-centered facts communications network (DCN) or in band by way of one in the LAN or WAN ports.

The Cisco ONS 15302 provides a small type aspect (only one RU) and is capable of terminating regular TDM and native Ethernet website readers, producing it an perfect services-delivery system. As proven in Determine 2, specific targeted traffic from as a lot as 12 E1 and 4 10/one hundred Mbps Ethernet interfaces is usually collected inside of a single Cisco ONS 15302 device to turn out to be transported back to the first position of specific site visitors aggregation on the service provider network. For Ethernet services, bandwidth can be configured individually for every single LAN port in 2-Mbps increments. This permits services suppliers to supply diverse ranges of service centered on every single customer's demands.
Ethernet much more than SDH Expectations Compliance
The Cisco ONS 15302 offers ITU-T G.7041-compliant Generic Framing Approach (GFP) encapsulation of Ethernet web-site site visitors for simple integration with recent SDH networks. The product or service also makes use of ITU-T G.707-compliant minimal-order and higher-get digital concatenation and ITU-T G.7042-compliant backlink potential adjustment scheme (LCAS), making it a ton much more beneficial for scalable, following-generation optical infrastructures.
Integrated Layer 2 Changing
The Cisco ONS 15302 has an built-in Layer two change that permits advanced management of packets for a number of purposes and network configurations, like info-traffic aggregation, and multipoint connections.
Versatile Network Topologies
The Cisco ONS 15302 can supply common E1 products and services at the very same time as native Ethernet readers for the customer premises much more than unprotected or linear one+1 MSP-guarded STM-one hyperlinks. Ethernet bandwidth can be configured individually on every single LAN port, only limited by the WAN ability, which could be as much as a full STM-one. Bandwidth could be extra individually for every port in 2-Mbps increments up to a utmost of 100 Mbps for Fast Ethernet. Lots of programs require a uncomplicated point-to-point connection - possibly straight or by signifies of an SDH network - among two Cisco ONS 15302 units through an STM-one circuit. Also, fairly a handful of branch workplaces may well be related to a headquarters site in a position-to-multipoint topology, the place every single department can have individually committed bandwidth. Added branches is often extra by stacking models at headquarters.
