1. INTRODUCTION
1.1 OCU DP OVERVIEW
one of the Option Modules available for use with the
ADTRAN TSU 100. The OCU DP is an all-rate Office
Channel Unit Dataport. It provides signal conversion
from any of the rates on the customer loop side to a
single DS0 time slot. The OCU DP should be selected
for use with the connection of DDS or Switched 56
DSU/CSUs or other equipment which utilizes a DDS
interface. The OCU DP provides an interface between
the T1 Multiplexer and a DSU/CSU over a 4-wire
loop, up to 18,000 feet in length of 26 AWG cable. This
interface permits the combination of DDS lines into a
single T1 stream.
1.2 FUNCTIONAL
DESCRIPTION
the TSU 100 and is subject to its operation and control.
The OCU DP is configured from the front panel of the
TSU 100 or by an external personal computer (PC)
program. The internal menus for its configuration are
a part of the OCU DP module and are automatically
installed when the OCU DP is plugged into the unit.

FEATURES
• Operates using one DS0
• 2.4, 4.8, 9.6, 19.2, 38.4, 56, 64 kbps dedicated rates
• Supports Switched 56 dial-up digital service
• Compatible with DDS secondary channel services
at rates ranging from 75 to 2400 bps, depending on
the primary channel rate
• 45dB range at all rates
• Transmit attenuation available for short loops
• OCU loopback toward TSU Network Interface (NI)
(front panel, remote, inband)
• Sealing current reversal to initiate loopback at the
CSU (front panel, remote, inband)

1.3 PHYSICAL
DESCRIPTION
The OCU DP, see Figure 1, is an option module
which plugs into the option slot in the rear of the TSU
100.

Figure 1. OCU DP Option Module
The OCU DP rear panel includes a plastic plug
over a cutout for additional connectors. This allows
a "plug-on" card to be added to the OCU DP module.
The PORT X.1 indication is linked to the port numbering philosophy of the TSU 100 product family. The X
represents the slot number, and the .1 indicates the
port number. For the TSU 100 application, there is
only one option slot. Therefore the port designation
for the OCU DP port will be 1.1. If added, the plug on
card port designation would be 1.2. These port numbers will appear in the front panel LCD menu displays.
