1.1 System Overview
1.1.1 General Overview
The Total Access
TM
1500 (TA 1500) is a Carrier Class, Multi-service Access Platform
for deploying narrowband and xDSL services from TDM or ATM backbone
infrastructures. A small, extremely versatile platform, TA 1500 integrates the
functionality of many carrier products into a single high-density chassis. TA 1500’s
small footprint (2U-high mounting) makes it the perfect choice for integrated
communications providers such as ILECs, CLECs, and ISPs, who need to deploy
services from crowded Remote Terminals (RTs), Central Offices (COs), or Co-
Location (COLO) facilities.
TA 1500 provides a variety of services including POTS, special services (ISDN, DDS,
FXO, FXS, E&M, DPO, DPT, and PLAR), and xDSL. TA 1500 complements
ADTRAN’s Total Access 3000 broadband multi-service access platform, which can
terminate and distribute higher bandwidth services such as SONET, DS3, HDSL,
HDSL2, T1, Optical DS2, and xDSL. TA 1500 can be deployed as a:
• Small Digital Loop Carrier (DLC), for simple and effective deployment of
POTS (up to 96 lines in a 2U mounting).
• Special Services delivery platform, with up to five times the density of any
competing D4 platform.
• Mini-DSLAM, serving up to 24 xDSL customers (POTS and data) using an
ATM network interface.
TA 1500 is a modular device, with five common slots and 24 access slots. Common
units required for operation are a Power Supply Unit (PSU), Line Interface Unit (LIU),
and System Controller Unit (SCU). A second, redundant PSU and LIU may be
deployed for added reliability. The PSU is available with an integrated Ring
Generator providing up to 20 REN ringing capacity. The LIU can support up to four
T1 interfaces and has full Time Slot Assignment (TSA) capability. This feature allows
users to “steer” varied amounts of bandwidth from the network to any of the access
slots, ensuring that no bandwidth is stranded. Future LIUs will provide HDSL2, fiber,
and ATM interfaces. The 24 access slots accept a variety of voice and data access
modules, allowing users to optimize their service for each application.
Using local or remote inband management, service providers can provision and
monitor the bank’s network interface and access modules. Transaction Language 1
(TL1) is used to communicate with Telcordia’s NMA
TM
Operations System
(OSS) using an internal X.25 PAD. An Ethernet 10BASE-T connector is used
for connection to SNMP networks. ADTRAN’s Total Access EMS
TM
software, run on an Openview workstation, provides a graphical user interface
(GUI).

1.2 System Components
Total Access 1500 is composed of five main elements:
• Total Access 1500 Shelf and Backplane
• System Controller Unit
• Power Supply Unit
• Line Interface Unit
• Access Modules
1.2.1 TA 1500 Shelf
The system houses the management, network interface, and access modules. The
compact shelf includes all the features necessary for total system functioning including
provisioning, protection, monitoring, alarm status, and testing. The single
multifunction backplane provides for a variety of system arrangements.
ADTRAN’s Total Access 1500 shelf is compliant with all applicable NEBS Level 3
requirements and listed to UL 1950 3rd edition.
All modules are inserted and removed from the front of the shelf. The two far left
slots are designated for the Power Supply Units (PSU). The next slot is designated for
the System Controller Unit (SCU). The next two slots are designated for the Line
Interface Units (LIU). The remaining 24 slots are reserved for access modules. Slot
openings are labeled for easy identification (see Figure 1.)
The 3.5-inch high, 12-inch deep, 23-inch wide shelf is constructed of heavy gauge
metal with vent perforations on the top and bottom planes. Reversible mounting
brackets allow for flush mount or 5-inch overhang configurations. Mounting brackets
meet both 1-inch and 1 3/4-inch mounting hole pattern.

1.3 System Connectivity
The TA 1500 fits in the standard 23-inch rack. The multifunction single backplane is
the key element in system versatility. It contains all I/O connectors, control and signal
routing, power input and ground, plus the interconnections between access modules
and the common cards. There are also facilities for plug-in modules and wire-wrap
pins for special purposes.
Refer to Figure 3, Total Access 1500 Backplane, to identify the locations of the
following:
1.3.1 System and Power Ground
1. Power Connections (TB1)
The system is designed to accommodate redundant power configurations.
Dual Terminals for -48V, return, and frame ground are provided. The system
will operate with each individual supply or both supplies functioning.
2. Ring Generator (TB2)
The system operates with either an internal or external ring generator. For external
ring generator applications, TB2 provides connections for ringing voltage, ringing
return, and frame ground.
1.3.2 Timing
1. Composite Clock (P14)
For applications requiring external timing sources, a composite clock interface is
available. SW1 allows the user to designate which bank is terminating composite
clock.
1.3.3 Network Interfaces
1. T1 Connections (P7, P8, P9, P10, P11)
Four T1s plus a protect T1 are available. A frame ground connection is provided
for each T1.
1.3.4 Loop Interface
1. Loop Access (P1, P2, P3, P4)
Loop side access is achieved via 50-pin amphenol connectors.
2. PGTC Connector (P5)
The Pair Gain Test Controller (PGTC) connector provides a 28-wire interface to
the Central Office PGTC. The Central Office PGTC permits customer loops
served by loop carrier systems to be tested from a maintenance center using
Mechanized Loop Testing (MLT).
1.3.5 Test Access
1. Loop Test Access (P6)
Four wire-wrap connections provide a metallic loop test bypass pair.

1.4.3 PSU/RGU
The PSU/RGU is a common module plug-in unit designed for use in the ADTRAN TA
1500 channel bank. (See Figure 6.) The PSU/RGU receives -48 Vdc from an external
source to provide all necessary voltages required by the other common modules and
access channel units. Through switchmode operation the PSU converts the incoming -
48 Vdc to regulated +5 Vdc, +3.3 Vdc and unregulated -7.5 Vdc, -26 Vdc, and -
48 Vdc for distribution to other modules. Two versions of the PSU/RGU are
available. The 1180007L2 allows the system to operate utilizing an external ring
generator. The 1180007L1 contains circuitry within the PSU that generates 105 Vrms
nominal, 20 Hz ring voltage for distribution to the channel bank’s voice cards.
Removing the 20 Hz, 5-amp GMT faceplate fuse disables ring voltage. Two PSU/
RGUs may be installed to provide fully redundant operation.
The PSU incorporates these features:
• Receives unregulated power input.
• Generates 20 Hz ring voltage (List 1 only).
• Faceplate mounted input power fuse
• Faceplate mounted ring voltage disconnect
• Faceplate status LEDs
• Provision free plug-and-play
The faceplate also includes LEDs for local module status.
