1. INTRODUCTION
The Total Access 900 Series products are Internet Protocol (IP) business gateways designed for
cost-effective deployment of up to 1.536 Mbps of Session Initiation Protocol (SIP), Point-to-Point Protocol
(PPP), or Frame Relay voice and data services. The Total Access 900 Series combines voice and data
services into a single platform for IP telephony service providers, such as competitive local exchange
carriers (CLECs), incumbent local exchange carrieres (ILECs), and Internet service providers (ISPs).
Total Access 900 Series products are built on the ADTRAN Operating System (AOS) platform and include
the AOS built-in IP router and firewall features. The units include a T1 network interface (
NET T1 0/1 ) or
an asymmetric digital subscriber line (ADSL) network interface (
NET ADSL 0/1
) (Total Access 904 and
Total Access 908 only), a DSX-1 interface ( DSX-1 T1 0/2 ), a VOICE interface (up to 24 foreign exchange
station (FXS) ports or 16 FXS plus 8 foreign exchange office (FXO) ports), a 10/100Base-T interface, and
a
CRAFT port (management interface). An optional battery backup is also available for the Total Access
900 Series. The last two digits of the product name indicate the number of onboard FXS ports. The Total
Access 904 contains 4 FXS ports, the Total Access 908 contains 8 FXS ports, the Total Access 912
contains 12 FXS ports, the Total Access 916 contains 16 FXS ports, and the Total Access 924 contains 24
FXS ports or 16 FXS ports plus 8 FXO ports with the octal FXO daughterboard. The units can provision,
test, and provide status for any of the voice and data interfaces. All connections are made using the rear
panel.
In common packet-based applications, the wide area network (WAN) (
NET T1 0/1
) connects to the ISP or
carrier’s network and transmits packetized voice and data over a SIP trunk. The customer’s voice is
presented as time division multiplexing (TDM) to the FXS ports or DSX-1 interface, and the data is routed
out the local area network (LAN) (
ETH 0/1 ).
