INSTALLATION INFORMATION
• An eight-position modular jack (labeled NETWORK) is provided to
connect to the network T1 circuit. The pinout is provided on this Quick
Start Guide. See
Chapter 2, Installation
,of the TSU User Manual for
more information. An eight-position modular jack (labeled CPE) is
provided to connect to the customer equipment. The pinout is provided
on this Quick Start Guide. See
Chapter 2, Installation
,of the TSU CSU
ACE User Manual for more information.
•The rear panel contains LBO dip switches for both the Network and CPE
interfaces. Detailed instructions on setting the switch positions are found
on the back of this sheet.
•The TSU CSU ACE can be powered by either of the following methods:
1. Use the included NEC Class 2, 12V at 400 mA wall mount power
supply.
2. Connect to a reliably grounded 12-48 Vdc source which is electrically
isolated from the AC source.
Note: The branch circuit overcurrent
protection shall be a fuse or circuit breaker rated 48V, minimum to
10A, maximum.
•Additional information can be found on the product CD which contains
the TSU User Manual, FAQs, Data Sheets, Applications, and White
Papers.

TEST AND MONITOR ACCESS
•Two monitor jacks are provided on the rear panel for bridging the
received signals to allow in service circuit monitoring.
•Four break-and-test jacks are provided on the rear panel for use in out-
of-service testing. These jacks bypass the connections of the modular
jacks. NET INand NET OUT are used to simulate the network input and
output of the TSU CSU ACE.To test the CPE, a T1 Bit Error Rate Test
(BERT) test set can be used to simulate the network. EQINand EQOUT
can be used to simulate the CPE with a BERT test set, allowing the
network to be tested. The TSU CSU ACE on the other end of the circuit
can be looped back to test only the network.
