adnLdrChanTimeSlotMask

Module: ADN-MIB

OID (symbolic): ADN-MIB::adnLdrChanTimeSlotMask

OID (numeric): 1.3.6.1.4.1.637.3.1.5.10.1.1.13

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This defines the bit location for framed subrate channels (G.703 (DS1 or E1) line driver only).

This object is not relevant to the v-series or FLIP (fake line internal preocess) line drivers which will respond to an SNMP Get command with a value of zero. This object is related to dsx1LineCoding in the DS1/E1 MIB.

For B8ZS (Binary-8 Zero Suppression) and HDB3 (ITU G.703 standard for E1 lines), the usual value is clear64Kbps, but the user can change this to any value.

For AMI (Alternate Mark Inversion), the usual value is b8jam56Kbps, but the user can change this to any value except clear64Kbps (because it would violate pulse density).

Note that the numerical values of adnLdrChanTimeSlotMask have been chosen so that they correspond to the one's complement of the bit mask used by the hardware.

clear64Kbps = Binary 00000000 b8jam56Kbps = Binary 00000001 b7jam56Kbps = Binary 00000010

Any additions to this object's values should follow the same principle. Common Name: Pulse Density Mask

What is adnLdrChanTimeSlotMask?

This read-only integer represents which time slots are active in a framed G.703 (DS1/E1) connection using a bitmask. For fractional T1/E1 circuits, engineers need to verify which 64kbps slots are actually allocated to their service. A timeslot mask of 0xFF (255) means all 8 time slots are in use, while 0x0F (15) means only the first 4 slots are active.

Examples

Walk all instances (SNMPv2c):
