MACIL access product DLC (Digital Loop Carrier) system offers FTTB (Fiber to the
Building), FTTC services. DLC is a unified network to provide both Narrowband (POTS, ISDN,
TDM Data) and Broadband services on a single fiber infrastructure. The DLC consists of a COT
(Central Office terminal) and a host of RTs (Remote Terminals) interconnected through a SDH
Ring. Use of WDM technology on DLC provides an overlay network for Broadband services on the same infrastructure. The RT is a self contained system with Transmission systems (SDH system), Access Channel Banks, Power Plants & Batteries, all terminations (FDF, DDF, MDF). The philosophy is the "Fiber-in to subscribers' services out. The broadband access products also include IP DSLAMs, B-RAS (Broadband Remote Access Servers, IP Ethernet switches and Routers.
  • Compact and low power
  • Available in slim or horizontal versions
  • Designed in with state of the art FPGA technology
  • Powerful Built In Test Equipment ( BITE ) facility.
Transmission SDH
MAC's PDH optical range of products multiplexes basic 2Mbps streams into 8/34/140 Mbps PDH streams as per a relevant ITU-T (G.703, G.742, G.751) recommendations. The multiplexed aggregate signal is converted into an optical signal at 1310 nm to be transmitted through a single mode optical fiber cable. The equipment configuration permits availability of stand- alone electrical multiplexers, optical line terminal equipments or regenerators. Large numbers of these equipments are deployed in Indian Department of Telecom network and also in other service providers.
Using the latest ADSL technology, MACIL offers IPDSLAMs for service providers a very cost-effective solution for immediate implementation of multiple services in private and public networks. MACIL IP DSLAMs enable people inside buildings to share the expensive uplink bandwidth and moves the Internet point of presence (POP) into the buildings. MACIL IP DSLAMs can also be used to ISPs through Ethernet Switches and Routers, since the IP DSLAM s terminates ADSL ATM circuits and converts the traffic to Ethernet-VLAN tagged packets. All Ethernet-VLAN traffic goes directly to ISP internal Ethernet environment, then be routed to the Internet.
