Sdi Ports - Nortel Meridian 1 Succession 1000M Installation And Configuration Manual

Table 31
Modem problems
Problem
CDR is not printing on an ESDI port
configured as 8 bits, no parity, and 1 stop
bit.
Modem is not communicating with the
Small System when the User is MTC, BUG
or CTY.
(The default setting of 8 bits, no parity, 1
stop bit is incompatible with the modem.)

SDI ports

Installing and connecting SDI and Ethernet ports
Table 31 lists some of the problems that may be encountered.
In the Small System, SDI ports are provided by the following cards:
• NTDK20 Small System Controller (SSC) card — provides three SDI
ports
• NTDK23, NTDK25 and NTDK80 Fiber Receiver cards — each provides
one SDI port
• NTAK02 SDI/DCH card — provides four ports, of which up to two can
be SDI ports
• NTAK03 TDS/DTR card — provides two SDI ports
Note 1: The functionality of the NTAK03 card has been incorporated
into the NTDK20 SSC card. However, you can also configure the
NTAK03 card, if required.
Note 2: There are several circuit cards that provide SDI port
connections in the Small System. However, only SDI port 0, 1, or 2,
located on the SSC card, can be used to access the system for the
Customer Configuration Backup and Restore (CCBR) feature.
Solution
Change the modem set-up to 7 bits, no parity, 1
stop bit, or add MTC or SCH to the ESDI user
prompt.
Change the modem set-up to 7 bits or the parity
to EVEN/ODD.
