Total Access 900/900e Series
IP Business Gateways
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 cost- 
effective, 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 
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.
Management
The Total Access 900/900e Series can be remotely- 
managed by either the ADTRAN n-Command®MSP 
or n-Command Enterprise Edition management 
platforms. ADTRAN n-Command platforms offer the 
ability to discover devices, makemass 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 industry-
leading, easy-to-use, Graphical User Interface (GUI).
Total Access 900/900e products are housed in a 
rugged metal enclosure; available in wallmount, rack-
mount, 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 industry-
leading 10-year warranty, free firmware updates, and 
ADTRAN’s world-class technical support.
