buffer used in the DTE and E-DCE modes (supported by modules KML.1 through KML.6 only).

This parameter is not displayed when the main link interface is DCE.

Designation Function Values

DSR&CTS Determines the handling of the DSR and CTS signals for the modules KML.1, KML.2 and KML.3.

When these signals are logically OFF, the transmit data line would be held to MARK.

EXT - When DSR and/or CTS signals are OFF, the transmit data line is held at MARK.

INT - The states of the external DSR and/or CTS signals are disregarded; and both signals are assumed to be

continuously ON (the transmit data is then not held to MARK when the state of either external line is OFF)

Default: INT

Default: EXT for KML.5 and KML.6 I TS CODE Selects the code transmitted to fill idle

(empty) time slots in the frames transmitted on the T1 or E1 line by the KML.7 and KML.8 modules.

KML.7, KML.8:

The available selections are 00 to FF (Hex.) Default: 00

FRAME Selects the multiframing mode for the KML.7 and KML.8 modules.

KML.7 module:

SF (D4) - 12 frames per multiframe ESF - 24 frames per multiframe Default: SF

KML.8 module:

G732N - 2 frames per multiframe G732S - 16 frames per multiframe Default: G732N

SYNC Selects the frame synchronization algorithm used by the KML.7 and KML.8 modules, and thus effects the time required to return to normal operation after local loss of synchronization.

CCITT - Complies with ITU-T Rec. G.732 (on the KML.8 module only)

62411 - As required by AT&T TR-62411 (after 10 seconds)

FAST - After 1 second Default: FAST CRC-4 Enables the generation of check bits in

accordance with the CRC-4 polynomial specified by ITU-T Rec. G.704 for the frames transmitted on the E1 line, and the checking of the check bits carried by the received E1 frames. This parameter is available only on the KML.8 module.

NO - CRC-4 option disabled YES - CRC-4 option enabled Default: NO

Designation Function Values

CODE Selects the line coding method used for zero suppression on the T1 link of the KML.7 module.

TRAN - Transparent (AMI) coding, no processing for zero suppression B7ZS - B7ZS coding

B8ZS - B8ZS coding

Note: Clear channel capability is available only with B8ZS coding.

Default: B8ZS FUNCTION Displays the function of the link interface of

the KML.7 and KML.8 modules.

On KML.7 module only:

DSU - The module has a DSU link interface

CSU - The module has a CSU link interface

On KML.8 module only:

DSU - The module has an LTU link interface

START_TS Timeslot number to start the frame of the external Kilomux. (Example: If the link frame rate is set to 256 kbps, then 4 timeslots are used. If the start timeslot is set to 5, the timeslots used would be 5, 6, 7, 8) DOWN_LOAD Selects the Kilomux management option INTERN DEDICATE_TS Timeslot number for timeslot to be used for

management

Valid if DEDICATED is selected in the DOWN_LOAD field

0

BPTS_16 Enables use of timeslot 16 for transmission of the Kilomux frame in G.732N frame mode.

KML.8:

YES NO

Default: NO DL_SPEED Defines the speed of management via TS0.

Valid if F-TS0 is selected in the DOWN_LOAD field

KML.8:

4 8 16 20 kbps Default: 4

Table E-2. Main Link Parameters (Cont.)

Designation Function Values

MASK Controls the transmit signal characteristics of the KML.7 module.

The displayed options depend on the link interface hardware (with or without CSU):

– When the link interface does not include a CSU, the transmit signal mask can be selected in accordance with the transmit line length, to meet DSX-1 requirements, as specified by AT&T CB-119, or set for compliance with FCC Rules Part 68A.

– When the link interface includes a CSU, the transmit signal can be attenuated by 7.5, 15, or 22.5 dB, to meet the requirements of FCC Rules Part 68A.

For link interfaces without CSU:

The following selections indicate the line length in feet:

FCC68A Compliance with

FCC Rules Part 68A Default: 0-133

For link interfaces with CSU:

0 - No attenuation

7.5 - Attenuation of 7.5 dB relative to the nominal transmit level

15 - Attenuation of 15 dB relative to the nominal transmit level

22.5 - Attenuation of 22.5 dB relative to the nominal transmit level

Default: 0 MAIN_LINK_

MODE Selects the operating mode of the KML.10

module. SWITCHED - Operation with ISDN switch

LEASED - Operation over leased lines Default: LEASED

ISDN

STANDARD Selects the service mode for KML.10

modules. 5ESS_POINT_TO_POINT - AT&T 4ESS

and 5ESS switches, point-to-point service 5ESS_MULTIPOINT - AT&T 4ESS and 5ESS switches, multipoint service

DMS-100 - Northern Telecom DMS-100 switch

NATIONAL-ISDN1 - Bellcore NI1 switch EURO_ISDN - ETSI Euro-ISDN NET3 NTT_ISDN - NTT Japanese ISDN implementation

Default: EURO_ISDN (NI1 for KML.10) B_CH Selects the B-channel used by KML.10

modules to carry the user's data when the main link rate is 64 kbps.

B1 - B1 channel B2 - B2 channel Default: B1
