Interfaces
The MAX has a number of interfaces on the base unit, and others are available on expansion
cards.
Interfaces on the base unit
Figure 1-1 on page 1-2 and Figure 1-2 on page 1-2 show the physical interfaces on the MAX
base unit.
POWER
The MAX accepts ac or dc power, depending on the model you purchased. Figure 1-1 on page
1-2 and Figure 1-2 on page 1-2 show ac power sockets. Figure 1-3 on page 1-2 shows the dc
power socket. (For further details, see Appendix B, “MAX Technical Specifications.”)
CONTROL
The control port connects to a VT100 terminal or a modem to provide the menu-driven user
interface to the MAX. The interface runs at 9600 bps (configurable through the user interface),
8 bits per character, no parity, no flow control, 1 stop bit. (For details about cables that connect
to this port, see “User interface specifications” on page C-1.)
LAN UTP
The LAN UTP port connects the MAX to an unshielded twisted pair 10/100 Base-T (UTP)
LAN. (For details about cables that connect to this port, see “Ethernet interface specifications”
on page C-4.)
SERIAL V.35 DTE port
The Serial V.35 DTE port provides a point-to-point connection between the MAX and another
device. In the MAX manuals, this port is called the Serial WAN port. (For details about cables
that connect to the serial V.35 DTE port, see “Serial WAN cabling specifications” on
page C-41.)
WAN (1 to 4)
The WAN ports are a group of either four T1 or four E1 ports providing point-to-point T1/E1
connections between the MAX and other devices. In the MAX manuals, these ports are called
Net/T1 and Net/E1 ports. (For details about cables that connect to the WAN ports, see “T1/PRI
interface specifications” on page C-4 and “E1/PRI interface specifications” on page C-13.
ALARM
The Alarm interface is a two-connector terminal block that provides warning of alarm
conditions. (For further information about the alarm relay, see Appendix B, “MAX Technical
Specifications.”)
