Customized firmware
The TG789VAC v2 now uses a customized firmware which better suits AT&T requirements and gives better on-site
configuration support. Most important elements:
•
The default user is now “ATTuser” , which after configuration only has user rights.
•
The gateway WAN connection is auto-sensing for ADSL and VDSL2 and enables’ the required connectivity
models. No reboot is required.
•
Embedded templates
◦
Bridge mode
◦
Austria; this model switches between ADSL with PPPoA to VDSL2 with PPPoE, and supports DHCP-
spoofing on both. This means the LAN attached client device can remain in DHCP mode and does not
need to be reconfigured. This device receives the public Internet address on its Wide Area Network
interface.
The configuration for specific countries will be done via external template files. These allow configuration as router
with support for Secure WiFi as well.

External configuration software
AT&T needs to support access in over 20 countries and wants to present the same hand-off and customer environment
in all situations. To support this AT&T has made external configuration software available via the AT&T global ftp
server, from which is can be downloaded. The software can be found via this URL:
ftp://ftp.attglobal.net/pub/MoW_Broadband/
The configuration options prepared are intended to support an ethernet attached IP VPN device for a small office or a
shop, or as standalone router with a dual-antenna wireless option. Both options can support IPv4 and IPv6 dual stack
environments. By default the AT&T IP DSL environment supports allocation of an IPv6 /128 prefix, and also a /60
Delegated IPv6 prefix to use for SLAAC or DHCPv6 IPv6 addressing on the LAN side of the router.
