1. INTRODUCTION

1.01 Dynamic expansion of DS3 transmission has challenged network planners and

engineers to seek new and practical ways to plan for this growth while maintaining network

performance at acceptable levels. DS3 network services have significantly impacted the

need for increased density in the DSX-3 arena.

1.02 This need for increased density is driven by the shortage of office space and a desire

to maximize new and existing line-ups while maintaining the DSX-3 pulse template,

voltage, and power requirements. As density has increased in DSX-3 products, cable used

to terminate these products has evolved from 728-type cable to smaller RG59/735-type

cables. Even with high density DSX-3 products and smaller coaxial cable; however, the

DSX-3 area continues to expand to larger line-ups in which the cross-connects are

exceed-ing the 27-foot limitation.

(3)

1.03 In order to address the issues of higher densities and equipment compatibilities,

interface standards such as Compatibility Bulletins, Technical Advisories and the American

National Standards have been established. The T1 Telecommunications Technical

Com-mittee, an accredited sub-committee of the American National Standards Institute (ANSI),

was established in 1984. ADC Telecommunications is an active member company of this

technical committee. Representatives making up this committee are manufacturers and

service and network providers who are working to establish interface standards for the

telecommunications industry.

2. GENERIC SYSTEM OVERVIEW

2.01 The DS3 transmission facility consists of several components that make up the

network. Of specific concern is the equipment typically located in the central office (CO)

where signals are handed off from carrier to carrier. Throughout this complex network, all

signaling eventually reaches a central location - the digital signal cross-connect (DSX)

point. The DSX forms a centralized cross-connect (digital distribution frame) for these

digital signals.

2.02 The DSX-3 system is designed for a specific signal level at the 45 Mb/s DS3 signal

rate. In a typical installation as shown in Figure 1, all digital equipment is terminated at the

DSX-3. In order to assure equal signal levels (equal voltage, power level, correct digital

pulse shape, and matching line impedance), output levels of all digital equipment are

equalized by customer-supplied components.

2.03 Several types of customer-supplied signal treatments to establish equal levels and

pulse shape characteristics are used to compensate for the effects of the transmission

medium. These include attenuator pads, equalizers, line build-out (LBO) networks,

match-ing networks, and automatic line build-outs (ALBOs).

2.04 The level of the signal applied to the cable pair must be set in accordance with the

physical location of the signal source along the transmission medium. This is done to assure

that equal levels of the signal traverse the cable in the same direction as the signal sources.

(4)

The advantage of equal-level transmission is that signals arrive at their destinations at the

same nominal level, therefore simplifying digital equipment processing, reducing

cross-talk, and minimizing mutual interference between adjacent channels.

2.05 Line build-outs (LBOs) and attenuator pads are used at the transmitter or source

equipment to pre-distort or pre-shape the transmission waveform. This compensates for

variations in cable length and other operational environments between the signal source and

the DSX equal-level point.

2.06 Matching networks are used to compensate for echoes caused by impedance

mis-matches. These irregularities are an important source of waveform distortion. Improved

impedance matching at junctions in the transmission medium is a good method for reducing

this type of signal distortion/variation.

2.07 Equalizers and automatic line build-outs (ALBOs) are used at the receive equipment

to establish the proper signal level and pulse shape required by the receiver. This is referred

to as the input sensitivity of the receiving device. An ALBO circuit followed by an amplifier

incorporates fixed equalization and gain. Typically, the fixed section incorporates the

appropriate gain and equalization for the maximum expected cable loss. The output of the

fixed equalizer is sampled by a detector that provides feedback to the ALBO section, adding

frequency-shaped loss until the total fixed and shaped output signal reaches the desired

value (see Figure 2).

2.08 These build-out networks and equalization techniques, in addition to the cable

characteristics, constitute the transmission environment. Cross-talk, noise thresholds,

trans-mitter power and receiver sensitivity are also key considerations in determining

perfor-mance requirements during network planning for any given transmission medium.

3. CABLE SPECIFICATIONS

3.01 Based on Bellcore Specification TR-NPL-000320 and ANSI Standard

T1.102-1987, cable characteristics have been used to establish a transmission loss budget that

includes 11 dB of insertion loss for IN and OUT cables, and 1.15 dB of insertion loss for the

(5)

3.02 The maximum distance from the transmission/multiplex equipment to the DSX

termination is 450 feet (137.16 m), depending on cable type. The maximum DSX

connect cable length has been established at 27 feet from the OUT to the IN circuit

cross-connection. Cable length from the DSX to the terminal equipment is also 450 feet,

maximum.

4. CABLE RECOMMENDATIONS

4.01 The maximum length recommended for IN and OUT cross-connect cables is based

on a generic cable; however, specific cables exhibit their own unique characteristics.

Figure 3 discusses the key cable-selection considerations and provides the formula used for

calculating the cable lengths listed in Table 1. Table 1 lists the system cable length limits for

IN/OUT cables and cross-connect cables for the DS3 transmission environment, based on

the already-mentioned 11.00 dB and 1.15 dB cross-connect frame budgets. The information

provided may be used as a rule of thumb for system planning and limitation approximations

based on variables designed into the network as a result of the cable type and DSX

equipment selected for the individual application. When cross-connects exceed

recom-mended lengths, DS3 intra-office repeaters should be used to ensure proper network

performance.

For 728 cable, A∅ = 2.574 dB loss for 100 feet of cable at 100 MHz.

(Ld)

Ld = (100)(0.484 dB) 2.574

= 39.757 Equal level transmission for the purposes of

minimizing transmission disturbances has been deployed in the network. This has resulted in establishment of the power levels and sensitivity levels of the transmit and receive equipment, as well as established the appropriate levels at the DS3 cross-connect. In addition, attenuation loss budgets have been established for the interconnecting cable and DSX-3 cross-connect.

The DSX-3 cross-connect is assigned an insertion loss budget of 1.15 dB, maximum, at 22.368 MHz, including the loss of 27 feet of cross-connect cable (728 or equal). The In/Out cabling insertion loss is assigned 11.0 dB at 22.368 MHz. This is based on actual cable measurements of AT&T 728 cable at a length of 900 feet.

The basis for these specifications results from attenuation of a coaxial transmission line. Assuming the transmission line follows an approximate ÷f (root frequency) law, the transmission medium insertion loss can be estimated using the formula shown at right if the following characteristics are known: Nominal attenuation for a specified length of cable at a specified frequency.

(6)

4.02 With the loss characteristics identified, a logarithmic curve was established and was

used to create a formula that determined the cable loss at specific frequencies.

4.03 ADC cautions against shortening the IN/OUT cables in order to further extend the

cross-connect lengths. Shortening the IN/OUT cables or removing the LBOs changes the

signal level at the DSX and may overload the receiving equipment, resulting in transmission

errors. Also, the signal will no longer be at an equal level. If the signal is out of equal level,

it will have an impact on the flexibility of the patching and cross-connect rearrangement at

the DSX-3.

4.04 Table 1 lists the eight types of cables that are used as cross-connects. Each cable type

was tested to verify the insertion loss characteristic. The cross-connect lengths were

deter-mined by testing the loss of 100 feet of cable from 10 MHz to 500 MHz (735A cable was

tested at 10 MHz to 300 MHz). The loss characteristics differ in each type of cable;

consequently, the maximum length for each cable differs. The specific cross-connect lengths

were determined by adding together the loss of IN/OUT cable (from equipment to DSX-3 and

from DSX-3 to equipment) and the loss of the specific cross-connect cable. Total system loss

budget allowed for the matrix (end-to-end loss) was 11.00 dB for IN/OUT cables and 1.15 dB

for the two DSX-3 modules and cross-connect patch cords, for a 12.15 dB maximum.

5.01 The insertion loss test diagram and graphs were used to determine the loss of the

DS3 cable found in the cabling matrix. Each cable was tested using a Hewlett Packard

4195A Network/Spectrum Analyzer and two 50-to-75 ohm minimum loss attenuators as

shown in Figure 4.

Step 1

Cut the coax cable to the proper length using the coax cutting tool.

Step 2

Slide the crimp sleeve onto the cable, placing it at least 6 inches (15.3 cm) from the end of the cable. The marked end of the crimp sleeve should face away from the cut end of the cable.

Step 3

Follow the instruction sheet included with the stripping tool for adjusting the cutting depth of each blade of the stripping cassette. Adjust the blade depths to cut the appropriate layers of the coaxial cable. The blades should not cut beyond the appropriate layer of the coaxial cable. (i.e., The blade that cuts the outer jacket should not cut into the braided shield and the blade that cuts the dielectric should not cut into the center conductor, etc.)

Some coaxial cables have a metallic foil shield under the braided shield. This foil shield shall be cut to the same dimen-sion as the braided shield.

Using the specified stripping tool and black stripping cassette, strip the layers of the coaxial cable. (See diagram.)

Step 4

Snip the center conductor so there is a measurement of 0.156 in. (3.9 mm).

Step 5

Place the connector’s center pin over the cable’s center conductor. Using the specified crimp tool and crimp die, crimp the center pin in place making sure the flange of the center pin butts against the crimp die.

To test the crimped center pin, moderately pull on the pin.

Step 6

While feeding the center pin through the ferruled end of the connector shell, slide the connector shell onto the cable. The connector shell’s ferruled end slides over the dielectric (and foil shield if present) and under the braided shield. Push the cable into the connector shell until the center pin locks into the connector shell. The connector shell should not easily slide off the cable when the center pin is locked into the connector shell.

Step 7

Slide the crimp sleeve over the braided shield until it butts against the connector shell. The crimp sleeve will cover approximately 0.125 inch (3.2 cm) of the cable’s outer jacket. None of the braided shield should be exposed between the crimp sleeve and the connector shell.

Step 8

Using the specified crimp tool and crimp die, center the die over the crimp sleeve and crimp in place.

To test the crimp strength, exert a moderate pull on the connector shell. Using company standard procedures, test for opens or shorts.

Place the center contact over the center conductor and crimp in place with the specified crimping tool.

Note: Be sure the flange on the center contact butts against

the crimping die of the jaw. To test the crimp strength, pull on the center conductor.

Step 6

Slide the BNC connector over the dielectric and under the braid until it is fully seated against the dielectric.

Step 7

Slide the crimp sleeve over the braid until it butts against the BNC connec-tor. The crimp sleeve should cover approximately 0.125 in. (3.2 mm) of the jacket. No excess shield should be exposed between the sleeve and the body.

Step 8

Using the specified crimping tool, center the die over the ferrule and crimp in place. To test the crimp strength, exert a moderate pull on the cable to test the strength and seating of the crimp connection. Using company standard procedures, test for opens or shorts.
