TDM Access (MAP)
Time Division Multiplexing (TDM) is the world's foremost communications infrastructure technology, playing a central role in transporting customer voice and data traffic. Microtel offers a wide range of TDM access products serving carriers and service providers, cellular operators, utilities and transportation, and government agencies.
TDM carries customer voice and data traffic for many specialized legacy applications not supported by packet-switched networks (PSN) or for which PSN does not offer stringent Quality of Service (QoS).
Our TDM access products are also ready for the evolution to next-generation networks (NGN), incorporating pseudowire (TDMoIP) technology for transporting all existing TDM services over packet-switched networks. TDM Access products available include:
Microtel have put together a portfolio of highly flexible and versatile multiservice access multiplexers to groom, aggregate and cross connect multiple services, including voice, ISDN, high/low speed data, and LAN over fiber optic, wireline, xDSL or wireless.
The range of multiplexers offer scalable products and feature a wide range of capabilities, including SDH/SONET ADM functionality, IP migration, voice compression, and flexible cross connect capacities, to fit the needs of small businesses, large organizations and carriers.
Many of our multiplexers are ideally suited to the utility and transportation industries, whose critical time and delay sensitive applications require the Quality of Service of TDM-based access and SDH transport solutions.
The units can be deployed at the customer premises and carrier points of presence (PoP).
Digital Cross Connects:
Digital cross connect products groom and concentrate fractional traffic from the user side into full E1/T1, E3/T3 or STM-1/OC-3 trunks for connection to central offices. Deployment of digital cross connect products for backhauling circuits enables the delivery of leased line services at lower capital and operational costs.
Available in a wide range of capacities, Micotels range of digital cross connects are deployed by cellular operators, carriers, utility companies, enterprises and ISPs.
TDM NTUs:
TDM network termination units (NTUs), offer a compact, cost-effective units for extending the E1/T1 network to the customer premises, enabling carriers and service providers to create a flexible, service-independent access model while offering a competitive and wide service portfolio.
Controllable from a single management platform, the NTUs are available with powerful demarcation features, offering a cost-effective and quick service deployment alternative for global carriers expanding their services over a third party’s infrastructure while offering extensive diagnostic capabilities.
Fibre Multiplexers:
Microtel have put together a best in breed range of fiber multiplexers that enable cost-effective and efficient transport of multiple E1 or T1 lines and Ethernet over fiber optic links.
Featuring ranges of up to 120 km (75 miles), the fiber multiplexers serve incumbent and alternative carriers, cellular operators, ISPs, utilities, transportation networks, large enterprises, and small and medium-sized businesses.
Typical applications include point-to-point and ring topology for campus networks, E1 fan out over satellite link, and drop and insert for cellular infrastructure.
SDH SONET Multiplexers:
SDH/SONET multiplexers deliver traditional PDH services over existing SDH or SONET networks, providing an ideal platform for extending multiple E1/T1 or E3/T3 tributaries.
The multiplexers combine the high capacity associated with SDH and SONET add-drop multiplexers (ADMs) with the simplicity and low cost of a terminal multiplexer, significantly reducing operating and capital expenses.
The devices are especially suitable for extending SDH and SONET network services to remote and suburban locations such as industrial areas and business parks.
SDH SONET ADMs:
Microtel have a range of SDH or SONET add/drop multiplexers allowing transport of TDM and next-generation Ethernet traffic over the SDH or SONET ring, leveraging the SDH or SONET infrastructure to provide Internet access and LAN connectivity in addition to traditional E1, T1 tributary services.
Deployed by carriers and service providers to leverage optical bandwidth for revenue-generating Ethernet services, enterprises, utilities and campuses also deploy SDH or SONET ADMs to provide LAN services over fiber optic infrastructure.
Inverse Multiplexers:
A range of intelligent inverse multiplexers bridge the gap between E1 and T1 lines and the need for expensive E3 or T3 links, enabling cost-effective transport of high-speed traffic over TDM E1/T1 links.
Our range of inverse multiplexers splits traffic onto multiple E1/T1 or SHDSL links, providing increased bandwidth where services higher than E1/T1 are either not available or too expensive. Some inverse multiplexers also transport Ethernet traffic transparently over multiple E1 or T1 lines.
For applications requiring connection of E1 equipment over T1 transmission facilities, inverse multiplexing technology enables the transmission of one standard E1 frame on 2 T1 links.
Sub-rate Multiservice Multiplexers:
The sub-rate multiservice multiplexer product line is for integrating data, voice, fax, and LAN over a single link. The multiplexers mix a variety of traffic types over leased lines, ISDN, IP, and fractional E1 and T1 lines, over copper or fiber, at data rates from 9.6 kbps to 1,536 kbps.
Combining award-winning, high-quality voice compression techniques with maximum bandwidth utilization and a wide range or network and user interfaces, the sub-rate multiplexers provide reliable point-to-point and drop-and-insert data/voice integration solutions at an affordable price particularly attractive to the transportation, utilities and governmental markets.
The low overhead, minimal end-to-end delay and allocated bandwidth of the sub-rate multiplexers, together with voice compression, ensure Quality of Service (QoS) while maximizing utilization of the available bandwidth.
The Sub Rate Multiplexers are modular devices and come with a large number of user and network interface modules, supporting high-speed and low-speed data, analog and digital voice, and various main links.
