Total Access 850 System Manual Section 1 System Description

1. SYSTEM OVERVIEW

The Total Access 850 is an integrated access device designed for cost-effective deployment of voice and data services at the customer premises. The Total Access 850 system benefits integrated communications providers, such as CLECs, ILECs, and ISPs, who require a customer premises device that integrates voice and data functions. It provides a viable migration path from TDM to packet-based technology (see Modules on page 18 for details). The Total Access 850 features remote management, an integrated IP router, and special services slots. Preconfigured Total Acces s 850 packages are available.

The Total Access 850 is a modular device with two common slots, six access slots for FXS, FXO, Dual V.35, and UBR1TE modules, and two slots for special access modules. The FXS, FXO, Dual V.35, and UBR1TE modules are supported in the Router Control Unit (RCU); however, the Bank Controller Unit (BCU) also supports E&M, OCU DP, Single DS0 DP, and Nx56/64 modules. Using local or remote inband management, carriers can turn features, functions, and access ports on and off. Easy access to modules, common modules, power supplies, and the battery back-up system simplifies maintenance procedures. Hot-swappable modules may be replaced without disrupting other units. The four-circuit-per-module design ensures that only four analog circuits are affected when replacing a module.

The Total Access 850 is a compact, NEBS-compliant cabinet suitable for the customer premises or the central office. The 2U design uses little rack space; or when wallmounted, the 8½-inch by 11-inch chassis occupies a space the size of a piece of notebook paper. Two Total Access 850 systems can be mounted side-by-side in either 19-inch or 23-inch relay racks.

The following is operational information pertaining to the Bank Controller Unit when used with the Total Access 850 system.

Faceplate LEDs

The faceplate Network LEDs labeled T1 NETWORK and T1 FRACTIONAL provide status information using a color coded message format. Table 1 gives a description of all faceplate LEDs for the BCU when used with the Total Access 850 system.

Table 1. BCU Faceplate LEDs

For these LEDs... This color light... Indicates that... Network/Frac T1 OFF there is no power to the system.

RED the unit is in Red Alarm (meaning the T1 is down, not

connected, or framing is improperly configured).

YELLOW the unit is receiving Yellow Alarm (meaning the far end

unit is in Red Alarm). Solid GREEN the unit is functioning normally. Blinking GREEN the network T1 interface is in Test mode.

DIP-Switch Settings

The Total Access 850 BCU can be provisioned from DIP-switches (S1) mounted on the PCB, or through screen menus accessed via the faceplate loopback options are found on the DIP-switch panel. Table 2 gives DIP-switch provisioning information. DIP-switch S1 must be provisioned without the BCU in the chassis. Once the BCU is installed, any software provisioning made will override the DIP-switch settings. If the BCU is withdrawn and reinserted (power-cycled), the software options remain in effect. If a DIP-switch setting is changed while the BCU is withdrawn, the new DIP-switch setting takes effect. If none of the DIP-switch settings were changed, the unit will be provisioned for the last software settings.

Faceplate TEST Connector

The faceplate TEST connector provides the necessary clock output required by standard DS0 Logic Test equipment (such as a TPI 108/109 test set). Specifically, the Test connector outputs 8 kHz and 64 kHz clock reference signal. DS0 test equipment is used to test DS0 access modules such as the OCU DP, DS0 DP, or UBR1TE. Once the test equipment is connected to the reference clock source, individual tests can be performed on DS0 access modules using the faceplate bantam jacks on each unit. Figure 3 on page 28 illustrates the DB-9
