isdnB1config(D4isdn)


isdnB1config -- ISDN physical layer and framing parameters configuration structure

Synopsis

   #include <sys/types.h>
   #include <sys/scoisdn.h>
   

typedef struct isdnBproto { ...

struct isdnB1config { isdnWord_t rate; isdnWord_t dataBits; isdnWord_t parity; isdnWord_t stopBits; } B1config;

... } isdnBproto_t;

Description

The isdnB1config structure offers offers additional configuration information for the B1 protocol specified in isdnB1proto(D4isdn). The complete B-channel protocol information is defined by isdnBproto(D4isdn).

Parameters

These parameters have different meanings and default values depending on the selected B1 protocol:

rate

B1 protocol 0:
not applicable

B1 protocol 1:
not applicable

B1 protocol 2:
the maximum bit rate, coded as an unsigned integer value. Default: adaptive.

B1 protocol 3:
the maximum bit rate, coded as an unsigned integer value. Default: 56 Kbps.

B1 protocol 4:
the maximum bit rate, coded as an unsigned integer value. Default: adaptive.

B1 protocol 5:
not applicable

B1 protocol 6:
not applicable

dataBits (bits per character/transmit level)

B1 protocol 0:
not applicable

B1 protocol 1:
not applicable

B1 protocol 2:
bits per character, coded as an unsigned integer value. Default: 8.

B1 protocol 3:
not applicable

B1 protocol 4:
the level is coded as a signed integer specifying dB's. If this parameter or its value is not supported by the ISDN controller, it is ignored.

B1 protocol 5:
not applicable

B1 protocol 6:
not applicable

parity

B1 protocol 0:
not applicable

B1 protocol 1:
not applicable

B1 protocol 2:
0 = none, 1 = odd, 2 = even. Default: no parity.

B1 protocol 3:
not applicable

B1 protocol 4:
not applicable

B1 protocol 5:
not applicable

B1 protocol 6:
not applicable

stopBits

B1 protocol 0:
not applicable

B1 protocol 1:
not applicable

B1 protocol 2:
0 = 1 stop bit, 1 = 2 stop bits. Default: 1 stop bit.

B1 protocol 3:
not applicable

B1 protocol 4:
not applicable

B1 protocol 5:
not applicable

B1 protocol 6:
not applicable
