 Remote terminal status in a CO/RT configuration

 Tone/pattern test generator and error detection

1.9 Loopbacks

The T1-S provides three different types of loopbacks.

 Near-End Line Loopback

 Far-End Line Loopback

 Far-End Payload Loopback (available in ESF mode only)

The near-end line loopback transmits information back to the customer or drop side. The two far-end loopbacks

require a remote control link between the near-end and far-end 360-80s. The far-end line loopback transmits both

data and overhead and is used to detect problems with the T1 line. The far-end payload loopback transmits data

only and is typically used to detect problems with T1 processing. The T1-S card also responds to all standard

CSU and T1 loopback codes.

1.10 Testing

The T1-S card provides test tones for analog voice card testing that can be enabled using the network manage-

ment interface. The T1-S also provides a random pattern generator and loopback code generator for testing data

cards.

2. INSPECTION

2.1 Inspect for Damages

Inspect the equipment thoroughly upon delivery. If the equipment has been damaged in transit, immediately re-

port the extent of damage to the transportation company.

2.2 Equipment Identification

Charles Industries’ equipment is identified by a model and issue number imprinted on the front panel or located

elsewhere on the equipment. Each time a major engineering design change is made on the equipment, the issue

number is advanced by 1 and imprinted on subsequent units manufactured. Therefore, be sure to include both

the model number and its issue number when making inquiries about the equipment.

2.3 Static Concerns

Each unit is shipped in static-protective packaging to prevent damages from electrostatic charges. Use approved

static-preventive measures, such as static-conductive wrist straps and a static-dissipative mat, when handling

units outside of their protective packaging. A unit intended for future use should be tested as soon as possible

and returned to its original protective packaging for storage.

STATIC-SENSITIVE

This equipment contains static-sensitive electronic devices. To prevent electrostatic charges from

damaging static-sensitive units:

 Use approved static-preventive measures (such as static-conductive wrist straps and static-dissipa-

tive mats) at all times whenever touching units outside of their original, shipped, protective packaging.

 Do not ship or store units near strong electrostatic, electromagnetic, or magnetic fields.

 Always use the original static-protective packaging for shipping or storage. Return a tested unit to its

original protective packaging for storage.

3. APPLICATION GUIDELINES

A typical application of the 360-80 Intelligent Channel Bank (ICB) system using the T1-S is to provide an interface

between the bipolar T1 signal from the public T1 network and data or voice interface units. The T1-S can inter-
