SCP-PLL733-010-03H Description
PLL-733 List 1 January 6, 2003 1
PRODUCT OVERVIEW
This practice describes the ADC®PG-Plus®PLL-733 List 1, a COLU that provides interfaces for four EBS
interfaces between an RT and the subscribers. An EBS COLU supports one RT, which supports 4 EBS sets with
up to three add-ons each (see Figure 1).
DESCRIPTION
A PG-Plus application provides bidirectional transport of multiple DS0 over a single, unconditioned wire pair
using HDSL technology. Using existing cable, PG-Plus provides for higher bandwidth needs of residential and
business customers by providing four EBS on a single HDSL twisted-pair wire. A minimally configured PG-Plus
application consists of:
•COTS
•COLU
•RT
Figure 1. Typical EBS Application
The COLU uses ADC's HDSL technology to provide digital transmission without the need for repeaters, loop
conditioning, or pair selection. The COLU can be installed in the PCS-718 19-inch or the PCS-719 23-inch COTS.
The COLU operates in the standalone mode with no other COTS circuit cards required. Advanced features such
as performance monitoring, alarm reporting, and testing require the addition of the PAU or the PMU. Line power
is provided to the RT by the COLU.
The COLU performs the interface functions between the EBS circuits of the CO switching system by mapping
one EBS line onto one DS0 for transmission to the RT on the HDSL pair. To obtain maximum reach, the HDSL
line to the RT is operated at the minimum rate to support the payload.
Because of the loop lengths supported by the EBS COLU, it does not support metallic fallback.

SCP-PLL733-010-03H Power Consumption and Heat Dissipation
PLL-733 List 1 January 6, 2003 3
POWER CONSUMPTION AND HEAT DISSIPATION
The three most important power demands of an COLU on the COTS input power are its maximum power
consumption, heat dissipation, and current drain. Table 1 lists the power consumption and heat dissipation for the
COLU on a per slot and COTS basis.
Maximum Heat Dissipation
The maximum heat dissipation measures the power converted into heat that is built up within the COLU. It
contributes to the total heat generated in the space around the COLU. This conversion factor is used to determine
the maximum number of fully loaded COTS per bay that will not exceed the maximum allowable power
dissipation density in Watts per square foot.
In CO locations, the maximum heat dissipation for open-faced, natural convection-cooled mountings is limited to
134.7 W per square foot per Section 4.1.4 of the NEBS standard GR-63-CORE. The footprint of a standard 16 slot,
23-inch COTS is 7.042 square foot. The maximum bay dissipation is therefore limited to 948.5 W. At 119.9 W
per COTS, the number of fully loaded COTS is limited to eight per bay with a heat baffle between every COTS.
Thermal Loading Limitations
The thermal loading limitations imposed when using the COLU in a CEV or other enclosures are determined by
applying the COLU power parameters to the manufacturer's requirements for each specific housing.
The worst case conditions under which these parameters are measured include a 15,000 ft., 26 AWG loop,
a fully loaded COTS, and a -42 Vdc COTS battery voltage, and 4 EBS phones Active. Loop current sink
at the COTS is assumed to be 16 mA.
Table 1. Power Consumption and Heat Dissipation
Power COLU Slot
COTS
19-inch 23-inch
Maximum Heat Dissipation
HDSL Line Power Off 2.1 W 25.2 W 33.6 W
HDSL Line Power On 7.5 W 90.0 W 119.9 W
Maximum Power Consumption
HDSL Line Power Off 2.1 W 25.2 W 33.6 W
HDSL Line Power On 12.3W 148.2 W 197.6 W
Maximum Current Drain
HDSL Line Power Off 50.0 mA 0.6 A 0.8 A
HDSL Line Power On 293 mA 3.53 A 4.70 A
This is a worst case situation in that it assumes the entire CO is subjected to the maximum power density.
Conditions other than the worst case ones presented in this practice would permit increasing the number
of COTS per bay without jeopardizing the CO thermal integrity. Consider also that, due to the chimney
effect, it is recommended to install one heat-dissipating baffle between every COTS. Otherwise, the rated
operating temperature of the COLUs may be exceeded.

Monitoring, History and Diagnostics SCP-PLL733-010-03H
4 January 6, 2003 PLL-733 List 1
Maximum Power Consumption
The maximum power consumption is the total power that the COLU consumes or draws from its -48 Vdc COTS
power source. This parameter is needed when the COLU is located remotely from its serving CO. It determines
the battery capacity required to maintain an 8-hour standby battery reserve for emergency situations.
Maximum Current Drain
The maximum current drain is the maximum current drawn from the COTS power supply when the COTS power
supply is at its minimum voltage (-42.5 Vdc). This determines the COTS fusing requirements.
MONITORING, HISTORY AND DIAGNOSTICS
COLUs provide extensive real-time, nondisruptive monitoring of HDSL transmission performance parameters for
all units in a circuit. You can select threshold settings for the performance monitoring measurements at the
appropriate COLU screen. These settings cause alarms to be activated at the designated threshold setting. The user
interface ports performance is also monitored. Monitored parameters include the following:
•HDSL Noise margin, pulse attenuation, ES, UAS
•Interface ES, SES, UAS seconds
•Major Alarm Relay Form-C relay contacts (NO, NC, C). Fail-safe operation
Performance Parameters
Based on the monitored parameters, the COLUs derive the following performance parameters:
•MAR A measure of the ratio of signal power to noise power, in decibels (dB), at a receiver point. A
value of 0 dB means that the predicted transmission BER is equal to 10-7, a value of 6 dB
means the predicted transmission BER is equal to 10-10. The Main menu status display of the
console continuously updates the margin value. You can set the high and low values of this
parameter for the COLU and the RT at the “HDSL Summary Screen” on page 16 and the
severity of the alarm at the “HDSL Alarm Types Screen” on page 28. You can see the results
of these setting at the “COLU Summary Screen.”
•LOSW The COLU has detected an error in one or more bits in six consecutive HDSL SYNC words.
Two consecutive SYNC words must be received without error to clear this condition. A
LOSW condition generally indicates the loop is down, thus data cannot be transmitted. The
COLU uses this parameter to derive UAS performance parameter. You can set the severity of
the alarm at the“HDSL Alarm Types Screen” on page 28. You can see the results of these
setting at the “HDSL Summary Screen” on page 16.
•HDSL ES An interval of 1 second during which at least one CRC is detected at the incoming HDSL port.
You can set the value of this parameter for the COLU and the RT at the “HDSL Alarm
Thresholds Screen” on page 27 and at the “HDSL Alarm Types Screen” on page 28 set the
severity of the alarm. You can see the results of these setting at the “HDSL Summary Screen”
on page 16.
•HDSL UAS An interval of 1 second during which a loop is down. You can set the value of this parameter
for the COLU and the RT at the “HDSL Alarm Thresholds Screen” on page 27 and at the
“HDSL Alarm Types Screen” on page 28 set the severity of the alarm. You can see the results
of these setting at the “HDSL Summary Screen” on page 16.

INSTALLATION AND TEST
The following sections describe the tools and procedure for installing and testing the COLU.
REQUIRED TOOLS AND TEST EQUIPMENT
No tools are required to install the COLU. For testing, the following tools may be utilized:
•EBS Telephone
•No. 2 flat-head screwdriver
•Optional, PSU-795, COTS Continuity Test Card, 150-1695-01 List 1
INSTALLING THE COLU
You can install the COLU in any slot except the three positions labeled COMMON, MUX 1, and MUX 2.
1Open the retaining latch on the front of the COLU.
2Insert the COLU into the card guides in a vacant slot in the COTS that corresponds to the location of the
wiring from the CO switch. Refer to the cabling tables provided in the COTS documentation for slot and
Telco cabling assignment.
3Engage the retaining latch to hold the card in place.
INITIALIZATION SEQUENCE
After inserting the COLU into the appropriate slot in the COTS, the following events should occur in the order
listed below:
•All the LEDs go On briefly and then go Off with the exception of the PWR and Fault LEDs, which start 1 Hz
Flash.
•After about 5 seconds, the COLU applies power and goes into Start-Up mode. If an RT is present and no
power feed shorts, opens, or ground faults are detected, the PWR LED is On green. HDSL Start-Up is
initiated.
•As the COLU continues with power-up mode (if an RT is present), the PWR LED is On solid and the SYNC
LED Flashes, indicating the HDSL line is attempting to acquire synchronization. When synchronization is
complete, the SYNC LED is On.
•The Margin LED is On yellow indicating the COLU signal-to-noise ratio is equal or below the selected
signal-to-noise ratio threshold on the COLU. The Margin LED flashes if the signal-to-noise ratio of the HDSL
line is equal or below the selected signal-to-noise ratio threshold on the RT. The Margin LED is Off when the
signal-to-noise ratio of the HDSL line crosses the selected signal-to-noise ratio. This takes approximately 30
seconds to 3 minutes, according to the loop length.
•Test each subscriber line with the test set. Observe the LED indicators for correct activity (where nequals the
EBS line):
–Off-hook (Active call): EBSnLED is On
–Ringing: EBSnLED Flashes at 8 Hz
–On-hook (no Active call): EBSnLED is Off

Subscriber Drop Tests SCP-PLL733-010-03H
8 January 6, 2003 PLL-733 List 1
There are three ways to initialize the HDSL on the EBS COLU, after the RT is installed:
•Wait 5 minutes for a Restart.
•Remove the COLU from the COTS and reinstall.
•Short the HDSL Tip and Ring pair for 3 seconds, remove short and wait 3 seconds.
SUBSCRIBER DROP TESTS
PG-Plus supports testing of a subscriber drop in two ways:
•Initiate a test by applying a test voltage on the Tip at the COLU through an MLT set
•With the VT-100 Terminal connected to the PAU or PMU maintenance port, select the Subscriber Drop Test
feature from the Test menu. Relays on the RT provide a path for performing a SDT. The results are reported
to the PAU or the PMU and presented as TA-909 resistive signatures.
