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).
VoIP Gateway
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.
Remote Survivability
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
calls may continue locally at the customer
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,
statistics necessary to troubleshoot VoIP calls over
the WAN to help ensure superior call quality.
delay, and packet loss
Management
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.
