Wireline Solutions

Cisco Broadband Local Integrated Services Solutions

Cisco Broadband Local Integrated Services Solutions (BLISS) allow service providers to deliver multiple data, voice, and video services over a common broadband access network. Cisco BLISS offerings demonstrate how service providers can deliver local telephony services to residential and small and medium-sized business customers using VoIP technology.
Cisco BLISS solutions are supported over a variety of broadband access technologies, including cable, metropolitan (metro) Ethernet, and T1/E1. Cisco BLISS solutions combine proven network components and structured network architectures to deliver innovative and profitable multiservice networks.

Cisco Voice Infrastructure and Applications

Cisco Voice Infrastructure and Applications (VIA) is a VoIP solution for service providers building advanced networks to lower network costs and rapidly deliver revenue-generating voice transport applications and services.
Cisco VIA extends network reach through worldwide compatibility. Its support for industry-standard signaling protocols such as H.323, Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), and H.248 make Cisco VIA the easy way to link a service provider's network to numerous interconnect partners and customers.

Mobile Wireless Solutions

Cisco Wireless Trunking Solution

The Cisco Wireless Trunking solution provides mobile wireless service providers an immediate return on investment by significantly lowering the cost of voice transport using sophisticated bandwidth-saving technologies. Many service providers have successfully used the wireless trunking solution as a first step in taking advantage of the IP/MPLS or ATM core network for transport of mobile voice traffic.

Cisco Wireless Transit and Gateway MSC Solution

The Cisco Wireless Transit and Gateway Mobile Switching Center (G MSC) solution provides a highly efficient mobile core network and dynamic routing of calls for Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA) environments. While providing the benefits of the Cisco Wireless Trunking solution, the Cisco Wireless Transit and Gateway MSC solution alleviates the MSC trunk and port exhaustion problem by efficiently routing the calls to their destinations.

Cisco Distributed MSC Solution

The Cisco Distributed MSC solution provides complete MSC functions, offering advantages over circuit switch-based MSCs. The Cisco Distributed MSC solution offers service providers many deployment options, including the placement of media gateways at the periphery of the mobile network, significantly reducing backhaul costs. In addition, the Cisco MGX 8880 Media Gateway helps enable deployment of revenue-generating packet-based services such as multimedia messaging and enterprise IP telephony.

Cisco IP Radio Access Network Transport Solution

The Cisco IP Radio Access Network (RAN) Transport solution allows mobile operators to optimize the critical transport segment between the cell site Base Transceiver Stations (BTSs) and the associated Base Station Controller (BSC) and Radio Network Controller (RNC) by using IP/MPLS transport to efficiently backhaul the traffic. This significantly reduces backhaul costs and improves cell site maintenance.
The Cisco MGX 8880 Media Gateway provides a smooth transition to support next-generation 3GPP- and 3GPP2-based wireless architectures for RAN aggregation and media gateways.
