Carriers are seeking cost-effective DSLAM
solutions to meet demand for additional
customer applications. The ADTRAN
TM
Total
Access
®
1250 is a temperature-hardened MiniDSLAM that enables delivery of 24 ports of
POTS and ADSL via an Ethernet 10/100Base-T
interface from smaller Central Offices (COs),
Controlled Environmental Vaults (CEVs),
Multiple Dwelling Units (MDUs), and Remote
Te r minals (RTs). The ADSL is derived from
the network interface and is combined via
onboard splitters with the existing POTS
service for single-pair subscriber delivery.
The Total Access 1250 offers a scalable
network interface today with the Ethernet
interface module. The IP interface module
supports 1483/2684 bridging via either
LLC/SNAP or VC MUX encapsulation.
Statistics are collected on both the subscriber
and network parts.
The compact, 1U high unit provides space
savings while offering multiple options for
placement within compact environments. Its
design leverages existing telco resources and
can be rackmounted, wallmounted, or vertically positioned within the RT. It measures
1.75 in. H x 17.25 in. W x 11.125 in. D and
offers redundant power using –42 to –56 VDC.
The Total Access 1250 is equipped with fan
modules and filters. Each fan unit is independently field replaceable. The fans are
controlled by heat-sensing circuits and will
run only when necessary. Front panel access
is available to all connections.
The ability to connect to the Total Access
1250 via an IP uplink at the customer premises immediately improves the economics of
broadband for businesses such as hotels,
service-based organizations, and small-tomid-sized enterprises (SMEs). Carriers benefit
by expanding IP in their existing networks
without costly ATM server installations. This
is especially true for network applications that
don’t require the expense associated with
ATM-QoS. In these cases, IP is more ubiquitous and cost-efficient for both intra- and
inter-network operations.
Management options include SNMP,
ACSII, TL1, Telnet, or local VT100 interfaces.
Menu-driven interfaces are simple and intuitive, ensuring a successful service
implementation through local and remote
access.
ADTRAN’s Total Access 1250 Mini-DSLAM
brings cost-effective and space-efficient ADSL
with POTS solutions to carriers providing
subscriber services at rural CO, MDU, CEV,
and RT sites.
