Dial-up modems for NAC connectivity
If the NAC system is beyond eight km (five miles) of the Meridian MAX
SNN/SNN-E’s VME multiport cable or the IPE/IPE-E’s four-port I/O
cable, then the dial-up connection method can be used. Dial-up modems
can be used with both the remote supervisor login and network link.
All modems for NAC connectivity to Meridian MAX are cabled in the
same fashion. This is outlined as follows.
NAC 2 end
The cable between the NAC, running a Meridian MAX SNN/SNN-E, and
the dial-up modem is a modem cable NT7D99AA. Figure 5-42 illustrates
this connection.
The cable between the NAC, running a Meridian MAX IPE/IPE-E system,
and the dial-up modem is a modem cable NT7D99AA. Figure 5-44
illustrates this connection.
Refer to the “Modems” section of the “Hardware installation” chapter of
Network Administration Center (NAC) 2.0 Installation

NAC 1 end
The RJ-45 end of the NT9D9007 cable is connected to the corollary

Figures 5-43 and 5-45 illustrate this connection.
Figure 5-46 shows the cabling arrangement for the NT9D9007 cable.
