pmxIfLayer1Mode
Module: BIANCA-BRICK-PMX-MIB
OID (symbolic): BIANCA-BRICK-PMX-MIB::pmxIfLayer1Mode
OID (numeric): 1.3.6.1.4.1.272.4.12.1.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: In T1 and E1 mode the primary rate interface is working with totaly different clock frequencies, framing and impedance. This depends on one of the jumpers on the PMX module. For correct operation all 5 jumpers must be in correct position.
E1 is normaly used in Europe and is similar to PCM30, 30 channels, 2 Mbit/sec, Impedance 120 Ohm
T1 is normaly used in USA and is similar to PCM24, 24 channels, 1.5 Mbit/sec, Impedance 100 Ohm
What is pmxIfLayer1Mode?
In T1 and E1 mode the primary rate interface is working with totaly different clock frequencies, framing and impedance. The pmxIfLayer1Mode field is read-only and indicates whether the interface is E1 (2 Mbps, 30 channels) or T1 (1.5 Mbps, 24 channels) per hardware jumpers. For example, typical values range from 1 to 10 depending on configuration.
