The PG-Flex Plus TM PCS-822 List 2A Field Shelf ( Figure 1 ) supports POTS, ADSL and ISDN services. ADSL is pro-
vided through Edge Internet Access Devices (IADs) and Remote Access Modules (RAMs). Any combination of up
to eight PG-Flex
Plus PLL-735 Dual Integrated Central Office Line Units (DICOLUs), eight PG-Flex Plus ALU-935 Asyn-
chronous Transfer Mode Central Office Line Units (ACOLUs), or four FLL-814 Flex Integrated Central Office Line
Units (FICOLUs) can be installed in the Field Shelf (
Table 1 ).
The PCS-822 contains eight 200 mechanics DS1 slots that provide up to 96 DS0s of Time Division Multiplex (TDM)
services and up to 128 PVCs for ATM services. These slots support external interfaces of T1, High-bit-rate Digital
Subscriber Loop (HDSL), or HDSL2. PCT-850 cards can also be placed in the T1 slots for feeding an external
