Index
Unique Index of the primary rate interface. The index
is similar to slotnumber * 1000 and is also refenced in 
the ifTable, the isdnIfTable and in the isdnStkTable
Selftest
The result of the initial selftest of the PMX module
If the result is not succesful, the module is disabled
successful(1)		All selftests succeeded;
acfa-failure(2)	failure with the module ACFA Chip
m32-failure(3)	failure with the module M32 Chip
mem-failure(4)	failure with the module memory
Enumerations:
  • successful (1)
  • acfa-failure (2)
  • m32-failure (3)
  • mem-failure (4)
Layer1State
The layer 1 state of the primary rate interface
active(F1)		active, framing and synchronisation
is o.k. This is the only state where
data-transmission is possible
remote-alarm(F2)	receipt of an RAI, remote alarm 
indication, from the remote side;
The remote-alarm is also known as
yellow alarm or distant alarm
no-signal(F3)		no signal is received, RAI will
be transmitted. NOS is also known
as red alarm .  
no-sync(F4)		signal is received but synchronistation
is not possible, RAI will be transmitted
The received signal may also consist
of contingous Ones
crc-error(F5)		signal and synchronisation are o.k. but
signal has heavy crc errors, RAI will 
be transmitted
power-on(F6)		initial state after power was   
switched on (transient)
resync(7)  		Setting Layer 1 State to resync can
be used to force resynchronisation
The Layer1states are also visible in the isdnIfTable, but
the state numbers are mapped to those of an BRI-Interface 
Enumerations:
  • active (1)
  • remote-alarm (2)
  • no-signal (3)
  • no-sync (4)
  • crc-error (5)
  • power-on (6)
  • resync (7)
Layer1Mode
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
Enumerations:
  • e1 (1)
  • t1 (2)
Layer1Framing
In T1 and E1 mode the primary rate interface can work  
with totaly different framing types on layer 1. The 
framing type must match the configuration of the 
first connected point e.g. the exchange or the NT 
e1(1)		E1 - minimum mode, CCITT Recommendation G.704
(Table 4a)  
e1-crc(2)	E1 , crc mode, CCITT Recommendation G.704
(Table 4b)  
e1-mf(3)	E1 , CCITT Recommendation G.704 (Table 4a) 
with Timeslot 16 multiframing enabled
e1-mf-crc(4)	E1 , CCITT Recommendation G.704 (Table 4b) 
with Timeslot 16 multiframing enabled
t1-esf(5)	T1 , Extended SuperFrame mode DS1
t1-d4(6)	T1 , AT&T D4 format DS1
t1-framings can only be set when pmxIfLayer1Mode is t1
e1-framings can only be set when pmxIfLayer1Mode is e1
The default framing for t1 is t1-esf, the default framing 
for e1 is e1-crc
Modifications of the default values are usualy not required.
Exceptions are only known for sweden and france (use e1)
Enumerations:
  • e1 (1)
  • e1-mf (2)
  • e1-crc (3)
  • e1-mf-crc (4)
  • t1-esf (5)
  • t1-d4 (6)
Layer1LineCode
In T1 mode the primary rate interface is able
to work with different line codes. 
e1-hdb3(1)      High Density Bipolar 3 Level Coding
This is the only valid linecoding for E1
t1-b8zs(2)      Bipolar 8 Zero Substitution
B8ZS refers to the use of a specified  
pattern  of  normal  bits  and  bipolar 
violations which are used to replace a
sequence of eight zero bits
t1-ami(3)       Alternating Mark Inversion. 
AMI refers to a mode wherein no  zero  code
suppression  is  present  and the line encoding
does not solve the problem directly.   In  this
application, the higher layer must provide data
which meets or exceeds the  pulse  density  
requirements, such as inverting HDLC data.
t1-linecodes can only be set when pmxIfLayer1Mode is t1
e1-linecodes can only be set when pmxIfLayer1Mode is e1
The default linecode for t1 is t1-b8zs
Enumerations:
  • e1-hdb3 (1)
  • t1-b8zs (2)
  • t1-ami (3)
ChannelMode
In T1 and E1 mode the primary rate interface may work  
with different channel types. Usually every timeslot
is similar to one channel but it is also possible to 
bundle multiple timeslots to one channel with a higher 
bandwith. This channel bundeling is currently not 
supported by the switching equipment for dialup 
connections of any network-provider. But usage is 
possible with leased lines.

from 16 to 31
