Copper and Fiber Access + Transport Platform Delivering Optimized Voice, Video and Data


MALC is a full-featured multi-service access platform optimized for delivering voice, data, and video services over a pure packet access network. MALC give carriers the flexibility to cost-effectively deliver triple play services over existing facilities and to migrate these services to a pure packet network. This migration is accomplished without disrupting subscriber service or revenue streams, giving carriers the ultimate flexibility for optimizing their networks and serving their subscribers.

Deployed in the Central Office, Remote Terminal, outdoor cabinets or basements, MALC offers a range of chassis options supporting densities from 24 to 960 ports per shelf. With provisioning and management common to all chassis, MALC minimize training, stocking, and operating expenses.

MALC enable service providers to deploy a wide variety of business and residential services in a single platform. MALC offers ADSL2+, ReachDSL, SHDSL, POTS, ISDN, T1/E1, and Pseudo-wire (PWE).

Enabling Residential & Business Services

The MSAP product line enables service providers the ability to offer high-end residential and business services on the same platform. Broadband, VOIP, IPTV, POTS, Ethernet and High Cap services can be offered over copper and/or fiber.


Service providers can leverage Zhone's flexible architecture to deploy different technologies such as POTS, xDSL, xPON, and EFM on its MSAPs in their Central offices or Remote Terminals. A range of form factors for all deployment sizes are offered.


The MALC chassis with its fault tolerant control software and redundant uplink hardware design increases the resiliency and the scalability of the product. It also offers Resilient Packet Ring (RPR) over Gigabit Ethernet to increase the reliability of the network.

Migration from TDM/ATM to IP

Software-selectable line and trunk interfaces provide elegant circuit-to-packet migration. A range of uplinks - including T1/E1 ATM (UNI and IMA), T1/E1 TDM (GR.303 and V5.2), SONET and Gigabit Ethernet - allow carriers to maintain existing TDM services while simultaneously retooling for VoIP services using SIP, MGCP or H.248 signaling. Moreover, Zhone's integrated ADSL+POTS technology eliminates cutovers and truck rolls by allowing carriers to provision broadband or narrowband services remotely.


The MALC product line integrates into Zhone's Management system (ZMS) giving the service provider total control over their entire network. Using ZMS multiple MALC nodes can be managed from remote locations, customer provisioning, fault isolation, Auto discovery, alarm aggregation and maintenance can easily preformed without any service interruption.

Cost Savings/Operating Costs

Zhone's MALC provides the functions of a Broadband Loop Carrier (BLC), DSLAM, VoIP Line Access Gateway and a GR-303/V5.2-compliant voice gateway. The MALC allows access network operators to deliver Triple Play services concurrently over copper or fiber access lines. This flexibility provides Operators with reduced sparing, training, management and installation expenses, hence reducing overall operating cost


The Zhone access portfolio is completed with a full line of outside plant cabinets completely engineered to support Zhone's MALC product line. Zhone's cabinet line has configurations that are designed to support small density to large scale deployments, with a full range of options designed to meet Service Providers needs.
