ADSL plug-and-play time arrives for DLCs
...On the other hand, if ADSL can be integrated with the access equipment already in place, network infrastructure changes will be minimal. Using their existing DLC and copper networks, carriers insert the ADSL channel unit into an empty space to create a remote digital subscriber line access multiplexer(DSLAM) within the remote terminal cabinet.
This avoids the need to undertake expensive and time-consuming new cabinet construction. Even the existing power supply can be used with this approach. And depending on the solution, integrated ADSL can be completely transparent to subscribers. They would replace their existing modem with a high-speed ADSL modem to have uninterrupted POTS and ADSL service.
The benefits of an integrated ADSL solution are not limited to just a DLC in remote situations. Because plug and play applies to the embedded switch as well as to the remote terminal, the same economies of scale can be realized in a CO-based environment.
For the implementation to be ubiquitous across both environments, a strong supplier of switching and DLC systems is required. This helps ease installation and training and reduce inventory because of the commonality of equipment and plug-in.
Integrated telephony and ADSL loop access vehicles add up to lower equipment and administration costs versus their overlay counterparts. For example, having POTS and ADSL originate in the same system allows a carrier to bridge onto a common tip and ring pair before hitting the metallic distribution frame. This eliminates the additional cabling complexities and their cost and administrative problems when POTS and ADSL originate in different systems.
Shelves can be deployed that can be equipped with POTS and ADSL as well as other services such as ISDN. In addition, new combinations of POTS and ADSL services can be packaged for subscribers.
Lucent Technologies and Westell Technologies have joined to produce an integrated ADSL solution that is ATM-based to help deliver the most economical bandwidth consolidation possible.The ADSL card provides two ADSL lines and an integrated onboard POTS splitter.
ATM statistical multiplexing is used to share the bandwidth provided by DS-3 feeder facilities among all the ADSL channel units equipped at the remote terminal. The DS-3 signal from the DLC is transported via a Sonet fiber multiplexer to the host system, where it is combined with other DS-3 signals into an OC-3c signal. The OC-3c signal then travels to the ATM backbone network...

Bell Atlantic to discount ISDN
PHILLIP J. BRITT
Bell Atlantic will offer discounts of up to 80% to businesses using its ISDN service, the company announced last week. Initially, Bell Atlantic will offer the discounts in Virginia, West Virginia, Pennsylvania and the District of Columbia and will consider similar offers for New York and New England.
"This palette of pricing choices meets our customers' requirements for predictable pricing for Internet access and for their employees who work at home," said Chris Pizzirani, a Bell Atlantic ISDN product manager. "Businesses that are connected over both B channels, eight hours a day, 22 work days a month can expect a total ISDN bill of about $125 for the service and local circuit-switched data usage."
Bell Atlantic needed a new pricing package to keep ISDN competitive with competitors' digital subscriber line (DSL) offerings, said Probe Research analyst Michael Smith. Bell Atlantic's own DSL deployment will probably fall short of its June target launch.
