TDM Services for Business Solutions
Solutions for Service Provider

TDM ServicesADTRAN offers a wide variety of market-proven solutions for TDM service solutions for business. This solution set includes industry-leading T1 multiplexing, voice and data aggregation and concentration platforms for backhauling, consolidating, and transporting TDM T1 and E1 services. In addition, ADTRAN is the market share leader in solutions for HDSLx and T1 service delivery and offers a wide variety of HDSLx/T1 access platforms, plug-in modules, and system management solutions. HDSL and T1 platforms and solutions address economic hi-cap services with a small footprint and integrated T1/HDSL/HDSL2/HDSL4 (HDSLx) service delivery. ADTRAN Total Reach technology allows for reliable, economical T1, DDS, and ISDN service delivery for applications such as extended loop deployments and distributed NGDLC.

HDSLx and T1 Service Delivery:

HDSLx and T1 Service Delivery

ADTRAN is the market share leader in HDSLx technology and has long been a provider of basic T1 components.

Today's HDSLx technology includes HDSL, HDSL2, and HDSL4 with each technology developed to meet specific, carrier needs. ADTRAN has been a leader in standards development for HDSL2 and HDSL4 technologies by closely working with standards committees.

HDSL2 and HDSL4 technologies have largely replaced T1 and HDSL (2B1Q), providing pair savings (with HDSL2) and DSL spectral compatibility. HDSL4 using four wires (two pairs) and up to three repeaters extends carrier reach beyond the Carrier Serving Area (CSA).

T-Scan is a feature developed by ADTRAN for HDSLx circuits that provides the user with remote management and fault isolation capabilities. T-Scan allows provisioning, performance, and event history information to be retrieved by the test center via the Facility Data Link (FDL). In addition, Tscan can be used to determine the nature and location of faults on DS1 trouble circuits.

MultiplexersMultiplexers:

M13 multiplexing remains an important part of network operations. ADTRAN's MX Series of M13 multiplexers provide carrier-class service in space-saving configurations and are the most cost-effective bandwidth consolidation solution in the industry. This line includes the space-saving (1U) MX2800 and the modular MX2820 chassis, supporting up to 9 DS3s for higher-density M13 deloyments. The MX2800 houses two hot-swappable controller cards that are capable of combining independent T1s, E1s, or T1s and E1s, on the same DS3. The two controller cards also provide built-in 1:1 redundancy for the DS1 and DS3 signals as well as redundant DS3 connections. Advanced diagnostics include CSU loopbacks, NIU loopbacks, C-bit loopbacks and built-in BERT (Bit Error Rate Testing) capabilities. A fully connectorized backplane means no wire wrapping and quick, easy installation. The MX2820 offers all of the same functionality in a chassis that can multiplex up to 252 DS1s.

Backhaul Traffic Between Central Offices

Backhaul Traffic Between Central Offices

The MX2800 is a useful tool for Competitive Local Exchange Carriers (CLECs) deploying voice and data services from co-locations within central offices. It provides a solution to backhaul the voice and data bandwidth back into their network.

Consolidating a T3 Using an M13 Multiplexer

Consolidating a T3 Using an M13 Multiplexer

ADTRAN offers cost-effective solutions with full redundancy options for multiplexing 28 T1s to DS3 or STS-1 (for SONET applications). The ADTRAN 2800 Series provides more options for the network designer to lower monthly operating costs.

Consolidating DS1s onto a DS3: M13 Multiplexing

Consolidating DS1s onto a DS3: M13 Multiplexing

The MX2800 is an economical M13 multiplexer with 1:1 redundancy for consolidating up to 28 DS1s over a T3. The MX2800 offers redundant AC or DC power and controller cards, and an optional integral modem is available for dial-up management.

E1 Over DS3

E1 Over DS3

The MX2800 supports G.747, the standard for deploying E1 over DS3 or STS-1. On a T3 circuit, three E1s are multiplexed onto seven DS2s, equaling 21 E1s. T1s and E1s can also be deployed together.

Total Reach (DDS and ISDN)Total Reach (DDS and ISDN):

ADTRAN’s Total Reach products incorporate the latest in loop technology to extend deployment ranges and eliminate the need for costly repeaters. Using 2-wire SC PAM based technology, Total Reach utilizes the existing copper plant more efficiently while saving costly labor expenses and reducing service order delivery times.

ISDN Support

ISDN Support

ISDN support in the Total Access 4303 PLUS brings GR-303 functionality to Total Access IADs. It gives the convenience of setting, activating, or taking down an ISDN line from the switch.

Total Reach DDS

Total Reach DDS

The Total Reach Office Channel Unit Data Port (TR OCU DP) is used in combination with the Total Reach Digital Data System-All Rate (DDS-R) termination unit to provide extended loop lengths, eliminating the need for DDS repeaters.

Total Reach ISDN

Total Reach ISDN

Total Reach extends BRI ISDN service over a single twisted pair up to 30,500 feet from the central office without repeaters. Total Reach ISDN is composed of a central office unit (TRI-C) and a remote unit (TRI-R) that use Simple Coded-Pulse Amplitude Modulation (SC PAM) to transport the 160 kpbs BRI information to the customer's NT1 or TA. 

Total Reach ISDN drastically reduces BRI service deployment time and the costs associated with equipment, installation, and high maintenance U-repeaters in extended loops. Installation of Total Reach ISDN products is quick and convenient.
