T1/E1 Link Activity Ports window 291
Models 2616RC, 3096RC & 3196RC Admin Reference Guide 20 • T1/E1 Link
• Near End Line Statistics—Show error statistics collected from the near-end of the T1/E1 line.
• Far End Line Statistics—Show statistics collected from the far-end T1/E1 line. Far End Line Statistics can be
used by devices that support the facility data link (FDL)
Link (dsx1LineIndex)
This object identifies a DS1 Interface on a managed device. If there is an ifEntry directly associated with this DS1
interface, it must have the same value as ifIndex. Otherwise, the value exceeds ifNumber, and is assigned a unique
identifier by following this rule: inside interfaces (equipment side) with even numbers and outside interfaces (net-
work side) with odd numbers.
Type (dsx1LineType)
This variable indicates the type of DS1 line using the circuit. The circuit type determines the bits-per-second rate
that the circuit can carry and how it interprets error statistics. The values are as follows:
• Other(1)—Link is disabled
• dsx1ESF(2)—Extended Superframe DS1
• dsx1D4(3)—AT&T D4 format DS1
• dsx1E1(4)—Based on CCITT/ITU G.704 without CRC (Cyclical Redundancy Check)
• dsx1E1-CRC(5)—Based on CCITT/ITU G.704 with CRC (Cyclical Redundancy Check)
• dsx1E1-MF(6)—Based on CCIT/ITU G.704 without CRC (bit oriented signaling)
• dsx1E1-CRC-MF(7)—Based on CCIT/ITU G.704 with CRC (bit oriented signaling)
• dsx1E1-Transparent(8)—Based on CCIT/ITU G.703 without CRC (Cyclical Redundancy Check)
Circuit ID (dsx1CircuitIdentifier)
This is the transmission vendor’s circuit identifier. Knowing the circuit ID can be helpful during troubleshooting.
