Remote diagnostic modems
The remote diagnostic allows Nortel to diagnose your Meridian MAX
whenever you experience difficulties. Often the solutions can be sent back
through this link directly to your system. Consult your service contract for
more details about the remote diagnostic service.
The following modems are supported for remote diagnostics:
• NetComm SmartModem M7F
• Racal VI2422PA
• UDS 2440
• UDS EC224A/D
• U.S. Robotics 28,800 Sportster
For the remote diagnostic modems, the following standards must be met:
• 1200 or 2400 baud rate
• auto-answer capability
• accessible from the public switch telephone network
The cable between the remote terminal and the diagnostic modem is a
straight-through DB-25 serial cable NT1R03Dx (male to male) or
NT1R03Ex (male to female). The type of cable used depends on the
configuration defined by the user.
Figure 5-7 illustrates this connection for a Meridian MAX running on an
SNN/SNN-E. Figure 5-8 illustrates this connection for a Meridian MAX
running on an IPE/IPE-E.
For an SNN/SNN-E, the cable between the Meridian MAX I/O panel and
the remote diagnostic modem is a DB-25 (male) to DB-9 (female) modem
cable, NT7D61Ax. This cable is connected to the I/O panel at Card 1, Conn
2.
For an IPE/IPE-E system, the cable between the Meridian MAX multiport
cable, NT1R03AA or NT1R03BA, and the remote diagnostic modem is a
straight-through DB-25 (male) to DB-25 (male) modem cable, NT1R03HF.
This cable is connected to the I/O panel at Port 2.
