Total Access 900/900e Series
ADTRAN offers a wide variety of solutions for converged voice/data services. The Total Access 900/900e Series of T1 and Multi-T1 IP Business Gateways are designed for carrier Ethernet and SIP/MGCP Voice over IP (VoIP) networks. These products feature all of the same robust routing and voice features of the widely deployed Total Access Integrated Access Devices (IADs), along with a host of new features and functions that enable costeffective, reliable IP service delivery. These devices use the ADTRAN Operating System (AOS) to simplify management and administration. Multiple models offer flexibility for varied applications from PRI delivery and trunking services to Hosted IP PBX offerings.
The Total Access 900 Series offers a single T1 network interface, while the Total Access 900e Series offers up to four T1s. User interfaces include up to 24 FXS ports for analog voice delivery, an integrated DSX-1 port for PBX connectivity (T1 CAS or PRI), and one (two for 900e) 10/100Base-T Ethernet interface(s) for access to the Total Access 900/900e's router or WAN access. The Total Access 900/900e Series can be coupled with a NetVanta Power over Ethernet (PoE) switch to provide connectivity to a variety of network devices and personal computers, as well as to power IP phones and Wireless Access Points (WAPs).
The Total Access 900/900e Series utilizes SIP or MGCP for VoIP applications, providing interoperability with industry-leading softswitches, feature servers, and gateways. Acting as a gateway, these devices convert IP signaling from the carrier into traditional TDM analog and digital voice services. This functionality allows the Total Access 900/900e Series to deliver voice services to both IP phones and traditional telephony equipment simultaneously. For customers implementing a hosted PBX or IP Centrex service, the Total Access 900/900e Series is ideal for providing customers additional analog ports necessary to support their remaining analog phones, fax machines, or modems. The Total Access 900/900e Series supports many popular calling features such as caller ID, call hold, forward, transfer, and call waiting. Voice Activity Detection (VAD) and silence suppression are supported and the flexible design allows the Total Access 900/900e Series to support additional CODECs as the market requires.
In addition, the Total Access 900/900e Series can act as a registrar and Back-to-Back User Agent (B2BUA) or as a SIP-transparent proxy to facilitate remote survivability and NAT traversal. In the event of a service interruption on the wide area network or if the carrier's call agent were to become unavailable, calls may continue locally at the customer premise between IP-based or analog phones.
QoS, Security, Routing, and Voice Quality Monitoring
The Total Access 900/900e Series uses the AOS to provide a stateful inspection firewall; NAT; DHCP server/client; and feature-rich, standards-based, IP routing functionality supporting BGP, OSPF, and RIP routing protocols. Inherent QoS methods ensure appropriate classification and prioritization of VoIP traffic. These methods include Low Latency Weighted Fair Queuing, class based weighted fair queing, support for Differentiated Services (DiffServ) protocol, Frame Relay Fragmentation (FRF.12), and Frame Relay traffic shaping. VQM captures Mean Opinion Score (MOS), jitter, delay, and packet loss statistics necessary to troubleshoot VoIP calls over the WAN to help ensure superior call quality.
The Total Access 900/900e Series can be remotelymanaged by either the ADTRAN n-Command® MSP or n-Command Enterprise Edition management platforms. ADTRAN n-Command platforms offer the ability to discover devices, make mass configuration changes or firmware upgrades, backup/restore configuration, and generate inventory reports for asset management. The ADTRAN n-Command MSP also offers VoIP VQM and reporting, as well as an industryleading, easy-to-use, Graphical User Interface (GUI).
Total Access 900/900e products are housed in a rugged metal enclosure; available in wallmount, rackmount, and desktop mountings; and offer a battery backup system for up to eight hours of uninterrupted service upon a customer-site power outage. Total Access 900/900e products are backed by an industryleading 10-year warranty, free firmware updates, and ADTRAN's world-class technical support.
