UTU-814 List 1B November 24, 1999 1
OVERVIEW
The PairGain® HiGain ETSI™Universal Termination Unit UTU-814 List 1B
is a programmable High-bit-rate Digital Subscriber Line (HDSL) unit that
can be configured as an LTU (master) or an NTU (slave). These LTUs and
NTUs are the Exchange Office and Customer sides, respectively, of a
repeaterless, DSX-1 (T1) and Nx64k (serial interface) transmission system.
The LTU-configured UTU-814 accepts the respective payloads through
DSX-1 and Nx64k ports and transports data to the NTU-configured unit at
rates of up to 1.544 Mbps (the standard T1 rate). The 1.544 Mbps payload is
allocated to the DSX-1 and Nx64k ports in time-slot increments of 64 kbps
each.
The DSX-1 interface conforms with ANSI T1.403-1989 and AT&T CB 119
standards. The Nx64k serial data interface complies with the V.35, V.36,
X.21, or RS-530 (RS-449) standard based on the selection made from the
console screen menus.
The NTU-configured UTU-814 can be locally powered by -36 to -72 Vdc or
line powered by a conventional LTU using less than 120 Vdc and 50 mA on
each HDSL loop. The LTU-configured UTU-814 is locally powered by -36
to -72 Vdc. The UTU-814 does not supply power to other HDSL units.
Supported application modes include Unstructured, Structured, Time Slot
Prioritization (TSP), and Single (single pair).
Point-to-multipoint, doubler, and protection switching applications are not
supported.
FEATURES
The UTU-814 List 1B has the following features:
•Application as both DSX-1 and Nx64k HDSL systems.
•Framing insertion for transmission of unframed data into T1 networks.
•Detection of standard CSU loop-up/loop-down codes.

REM LPBK LED Displays remote (REM) loopback state.
REM LPBK button Activates the remote interface loopback (V.54 loop 2).
V.24 (RS-232) console
port
Provides bi-directional communication between the unit and
an external maintenance terminal through a V.24 (RS-232C)
interface to allow configuration and performance monitoring
through the console screen menus as described in “System
Configuration” on page 9.
DSX-1 access jacks
LINE Provides splitting jack access to (XMT) and from (RCV) at the
DSX-1 interface. Breaks the XMT and RCV paths to permit test
signal insertion and retrieval.
BRG Provides non-intrusive bridging jack access to (XMT) and
(RCV) at the DSX-1 interface. Allows the two T1 payloads to
be monitored.
Bar code label Contains the serial number and part number of the line card,
as indicated in both bar code and text format. Also contains
the configuration number of the line card, as indicated by
"CFG: Rnn," where nn is the configuration number. For
example, CFG: R07 would indicate line card configuration
number 07.
Configuration label Contains the configuration number of the line card, as
indicated by Rnn," where nn is the configuration number. For
example, R07 would indicate configuration number 07.
