Expansion Architectures in DSLAM Central Office SolutionsSubscriber pricing has become the all-important issue in today’s DSL offerings. How todeliver DSL at the lowest per-subscriber cost is key. Recent technical developments haveadded expansion architectures as an effective tool to maximize subscriber density andminimize costs without replacing existing DSLAMs.
When considering a high-density DSLAM, service providers should also consider flexibilityof service, scalability, space, and cost per port. These are all critical factors that greatlyimpact service provider ability to expand DSL delivery throughout their customer base.
The ADTRAN Total Access 3010 DSLAM is a cost-effective, compact, high-density solutioncreating DSL expansion opportunities in areas that were previously considered noteconomical.
The Total Access 3010 HDX (High Density eXpansion) architecture provides a single systemsolution for networks that demand seamless, high-capacity solutions for the central office.

Central Office Exhaust and Expansion. With the height-
ened interest in DSL promotion and delivery, many offices
have exceeded the capacity of initially deployed DSLAMs. The
Total Access 3010 HDX (High Density eXpansion) architecture
brings new advantages to central office capacity concerns.
ADTRAN’s HDX architecture keeps expansion costs in check by
allowing shelf-by-shelf growth, coupling low initial costs with
per port costs that actually decrease as systems are added. A
single HDX system can support 1,056 DSL ports with a
common network interface and a single IP address.
IMA/ATM Aggregation. Many DSLAMs utilize multiple E1s
to transport user data to the centralized switch or router to
interface the Internet. Multiple E1 interfaces can exhaust the
port capacity of a router long before any router processing
limitations are reached, causing expensive, inefficient usage of
network resources. The Total Access 3010 is commonly used
throughout the industry to aggregate up to 88 E1s in a single
DS3 or STM-1 interface, minimizing router port requirements
and increasing overall system efficiency. The same Total Access
3010 can also provide subscriber access through ADSL,
SHDSL, and E1 interfaces while simultaneously providing IMA
aggregation services.
The HDX Architecture utilizes two system chassis:
1. Total Access 3010 DSLAM
2. Total Access 3060 Splitter Shelf
The Total Access 3000 DSLAM is a carrier-class, full-service,
temperature hardened DSLAM ideal for CO and large RT
applications. It provides full DSLAM functionality serving
up to 176 ports in only ten inches of rack space. The Total
Access 3010 DSLAM also provides edge switch capability,
offering E1 IMA and DS3 aggregation. The Total Access
3010 DSLAM HDX architecture scales port capacity from a
single chassis, 176 port system to a multichassis configura-
tion serving up to 1,056 subscribers.
The Total Access 3060 DSLAM Splitter Shelf houses 22 octal
splitter modules for POTS access and complements the
installation of the Total Access 3010 DSLAM. Cabling is neat
and simplified for ease of installation.
The ADTRAN Total Access 3060 accommodates other
services deployed from the same chassis including SHDSL,
IMA, IDSL, E1 Frame Relay, Circuit Emulation Services, and
E1 by utilizing a cut-through module in the corresponding
splitter chassis.
