DIP Switches S1 - S8

The configuration switches on S1 - S8 may be set to allow config-

uration for a wide range of applications. Default settings of S1 through

S8 are shown in the table below. Descriptions of each switch follow

the table.

Switch SW1: Line Coding

Use Switch SW1 to control the Network Line Coding options. Set

these options to be the same as the Line Coding given to you by your

Service Provider. If you are using two Model 2715RCs together as

short range modems, set both units identically, preferably to HDB3.

SW4 Line Framing & Coding

Off HDB3

On AMI

Line Coding Options:

High Density Bipolar 3 (HDB3): In HDB3 coding, the transmitter

deliberately inserts a bipolar violation when excessive zeros in

the data stream are detected. The receiver recognizes these

special violations and decodes them as zeros. This method

enables the network to meet minimum pulse density require-

ments. Use HDB3 unless AMI is required in your application .

Alternate Mark Inversion (AMI): AMI coding does not inherently

account for ones density. To meet this requirement, the user

should ensure that the data inherently meets pulse density

requirements.

3.0 CONFIGURATION

Two cards make up a single Model 2715RC G.703 Converter - a

front function card and a rear interface card. Each may require config-

uration depending upon the product application. This section describes

the location and orientation of the Model 2715RC’s configuration

switches and jumpers, and provides descriptions for all settings.

3.1 FRONT CARD CONFIGURATION

The Model 2715RC front card has a single bank of eight DIP

switches located on the top of the printed circuit board. Figure 1,

below, shows the position of the switches on the board.

Figure 2 shows the orientation of the DIP switches with respect to the

“ON” and “OFF” positions.

Switch SW2: CAS Multiframe

CAS multiframe uses Timeslot 16 (TS16) to send multiframe (MF)

alignment data. In CAS MF, a multiframe is defined as 16 frames,

where a frame consists of 32 64kb/s timeslots, numbered 0 to 31.

TS16 of the first frame in the MF contains the CAS MF alignment word

in the upper four bits. The alignment word is always 0000 (binary). The

2715RC does not perform any signaling in TS16 other than to insert

the MF alignment word, in order to maintain MF alignment. When CAS

MF is disabled, the unit transmits user data in TS16; therefore, up to 31

channels are available for user data. When it is enabled, TS16 is not

available to the user. In this case, the user can use up to 30 channels

for data. CAS MF can be used with CRC-4 MF or by itself. When en-

nabled, both units must employ CAS MF; if one unit is set for CAS MF,

and the other is not, the one using CAS MF will detect a loss of sync.

SW2 Option

Off Disabled

On Enable

Switch SW3 & SW4: CRC-4 Multiframe/External Clock Mode

In framed mode, SW3 is used for CRC-4 MF. CRC-4 Multiframe

uses Time Slot zero to carry CRC-4 information. It operates independ-

ently of CAS MF. When CRC-4 is enabled, the unit monitors the incom-

ing data stream for CRC-4 errors. It transmits CRC-4 error counts to

the transmitting unit. Excessive errors may cause loss of frame or loss

of sync. If CRC-4 MF is used, both units must be set for set for CRC-4

MF. Otherwise, the one using CRC-4 MF will detect loss of sync.

In unframed mode, SW3 is used along with SW4 to determine

the clock mode. In unframed mode, the model 2715RC can be set to

Network, internal, or external clock mode.

In framed mode SW4 is used alone to determine the 2715RC

transmitter timing. In framed mode, the Model 2715RC can be set to

Network or Internal Clock Mode.

The following charts represent both cases.

CLOCK MODES

Network Clock Transmitter timing is derived from the received line

signal.

Internal Clock Transmitter clock is derived from an internal source

clock.

External Clock Transmitter timing is derived from the local DTE

device.

Note: When using the 2715RC as a high-speed short range modem,

one unit of the link must be configured in either internal or external

clock, and the other end must be configured for network clock mode.

Switches SW5, SW6, SW7, and SW8

Use Switches SW5, SW6, SW7, and SW8 to set the DTE data rate.
