100 Testing ISDN BRI functions
D-channel packet data terminals communicate at a baud rate of up to 9.6
kbps. The packet data is multiplexed onto a 64 kbps BD that is linked with
the external packet handler through a dedicated ISDN PRI B-channel, or,
in the case of the MPH, through a dedicated connection.
In addition to configuring the MISP and the DSL in LD 27, ensure the
following:
•

•
See ISDN Basic Rate Interface Feature Fundamentals (NN43001-580) for
a detailed description of how to configure relevant ISDN BRI packet data
transmission parameters in LD 17, LD 16, and LD 14.
Procedure 37
Perform a B-channel packet data transmission test using an external packet
handler
Step

Note:
To perform packet data transmission verification, the system
must be connected to a DPN-100, or configured with MPH. Also, packet
data transmission functions must be selected when configuring the
B-channel and D-channel transmission characteristics. Use LD 27 to
specify the packet data transmission functions. See "MISP configuration
procedures" in ISDN Basic Rate Interface Feature Fundamentals
(NN43001-580).
the ISDN PRI loop carrying packet data was configured in LD 17
the packet handler route was specified in LD 16
an ISDN PRI channel for the packet handler route was configured
using LD 14
Action
From an ISDN BRI B-channel packet data terminal, dial another
local or a remote ISDN BRI packet data terminal and establish
an active call connection.
After the call-originating ISDN BRI terminal receives an
acknowledgment that the receiving ISDN BRI terminal is ready,
the call-originating ISDN BRI terminal can begin transmitting
packet data.
Verify that the transmitted data is received successfully by
checking the transmitted information for accuracy. Read the
information on the screen or print it on the local printer.
Release the connection.
