T-APS-R

T1/E1 Protection Switch

1150069

General Description

Dataprobe’s Model T-APS-R Automatic Protection Switch allows for protection of T1 or E1 circuits. The
Model T-APS-R can be used for protecting switch full or fractional services, as well as single ended
applications. The unit can be configured for use in Framed or unframed network protocol applications.
It is designed for use with redundant circuits and automatically switches paths in order to maintain
service. The T-APS provides both serial and Ethernet connectivity for remote access and is SNMP
compatible. Local and remote alarm notifications are provided for circuit failures.

RUN LED: While running properly, the RUN display light should be blinking.
1+1/1:1 LED : The LED will be on when the units are set in the 1:1mode. The 1:1 LED is off when the

units are set in the 1+1 mode. While the LOOK IN function setting is ON, the 1:1 LED will be blinking when
the CPE side had a fault.

E1 LED: It will be on in the E1 setting.
T1 LED: It will be on in the T1 setting.
L1 LED: It will be on if L1 is on active path.
L2 LED: It will be on if L2 is on active path.

Blinking events:

First setting the L1 as the active and L2 as protection path, the L1 light will be on and L2 light will be off. In
the event of automatic switch to L2, the L2 light will flash quickly before L1 light turns off. The L2 light will
then be on and L1 light off if switching succeeds.

In the event of fault from CPE side in L1 active and L2 protection path setting, the LOOK IN Function will
apply (see Setup, Selection B LOOK IN ). Setting the LOOK IN Function On will indicate the CPE side
fault by showing L1 light on and 1:1 LED light blinking.

In the event of L2 protection path fault, the fault is also indicated as L1 light on and L2 light blinking. The
fault from CPE failure or L2 fault can be easily distinguished by MEASURE ERROR RATIO function.

LOS LED: Loss Of Signal light will be on if the connection is lost of signals.
OOF LED: Out of Frame light will be on if the connection is out of frame.
AIS LED: Alarm Indication Signal light will be on when alarm signal received.
RAI LED: Remote Alarm Indication light will be on when remote unit fault received
Fail LED: Failure Light will be on if a system fault or a circuit failure occurs.

Installation
Nest Shelf

Turn off power source until all connection are completed.

Power

Connect -48VDC from A source and B source (if available) to terminal block positions marked -48A and ­48B located on the upper left rear of the chassis. Connect the +48VDC return for each source to the
terminals marked GND (A) and GND (B) respectively. Connect the frame ground to position marked
FGND.

An external 110-220VAC AC power supply option is available for powering the T-APS-R-15 on AC power
source. Dataprobe Item# 1930073

Network
Connect your network to the 8 wire modular jack marked LAN located on the lower left rear panel using a

pin to pin, non reversing cable. Wiring detail is shown below.

Serial

Connect an RS232 DTE terminal device to the RJ11 jack marked COM located on the left side of the
rear panel. See wiring detail below

Expansion

An RS-485 BUS is provided for expanded the communication bus to multiple nests. Be sure to connect
point A to point A, point B to point B, from HOST / MASTER to each SLAVE SHELF and SW1 is correctly
set.

Alarm Contacts

Alarm contacts are provided on the rear panel for indicating a hardware failure alarm (NC-COM).
Additional alarm information is available thru the network or serial ports

1+1 End to End or Single Ended Full T Service application. Data sent on both Active and

Protection Path. T-APS duplicates CPE Tx data on both lines and the better quality line is se lected
at each end.

1:1 End to End Fractional T Service application. Data sent on Active Path. Protection Path used for
circuit performance and communication between T-APS units. Units use the same line at each
end.

Blind 1 Independent operation. T-APS communicates to remote site on unused path to monitor
circuit performance. Can be used with other APS type devices. Monitors for loss or degradation
of CO signals on Active line and transfers to Protection Path. Monitors status or Protection Path
from LOS only when the path not in use.

Blind 2 Independent operation. No communication between T-APS unit or equipment at
remote site. Can be used with other APS type devices. Monitors for loss or degradation of CO
signals on Active line and transfers to Protection Path. Does not monitor condition of
Protective Path when not in use.

Redundant CPE Applications

The T -APS can be used for switching a T1/EI circuit between two sets of CPE for redundant equipment
operation. The Working Mode selection can be either 1+1, Blind 1 or Blind 2.

In the 1+1 and Blind 1 modes, TX signals from the CO will be present at each of the two CPE devices.
In Blind 2 mode only the current selected working path will see the TX signals. The alternate path will not

provide TX to it’s associated CPE while the Protective Path is working.

the protection path.

Enable: T-APS-R will be enabled to check CPE signals. In the event of excessive bit

errors from the CPE side to T-APS-R, T-APS-R will not perform switching. Enable
Look-In may increase a few mili-second to the switching time.

Automatic Switching

Once the bit error exceeds the preset threshold value or other connection failures, the
system will automatically switch from Active path to Protection path.

Manual Switching

Once the bit error ex ceeds the preset value or other connection failures, the system can
be switched from Active path to Protection path manually.

Line 2 as Primary Active path.

Set Recovery Time

Selections: 00 to 99 MINUTES

Setting the time interval to recover from protection path to the active path. Default: 2 Minutes.

Setting Recovery at 00 Minute: When Active Path experiences bit errors or lost signals, it
will switch to the Protection Path. The Protection Path will immediately switch back to
Active Path when Active Path is in a good condition.

Setting Recovery at 1 to 98 Minutes: When Active Path experiences bit errors or lost
signals, it will switch to the Protection Path. The Protection Path will switch back to Active
Path after Active Path stays in good condition for set number of minutes .

Setting Recovery at 99 Minutes : When Active Path experiences bit errors or lost signals,
it will switch to the Protection Path. While setting Recovery at 99 Minutes, the Protection
Path will not switch back to Active Path. The Protection Path will only switch back to
Active Path when experiencing excessive bit errors or lost of signals.

Current Settings

The Set up Menu screen will be display the current line card configuration. Selecting YES will store the

SNMP Ethernet Port

The system can be managed by SNMP through standard management software. Dataprobe provides a
private MIB wh ich is available on our web site at: http://www.dataprobe.com/files/switch/taps/taps-r.mib
Traps can be programmed to respond to various application requirements as well a operational functions
set and system status retrieved.

Setting I/P Address

The T-APS comes with factory installed IP address 192.168.1.254. In most cases this will need to be
changed.

Consult your Network Administrator to determine the appropriate IP address. The IP address is changed
thru the Set Uo menu screen .

To set the IP address, the hardware (MAC) address must be known. This address is located on a label
on the back of the unit or can be accessed thru serial port. The syntax for the MAC address is: nn-nn-nn­nn-nn-nn

IP Address, Subnet Mask and Gateway: Enter the appropriate information in dotted decimal format
(xxx.xxx.xxx.xxx). If you are unsure of the entries, consult your network administrator.
