Getting Acquainted with the MAX
Upgrading memory and compression modules
MAX 3000 Installation and Basic Configuration Guide
1-7
MAX 3000 T1/PRI
WAN ports 1 and 2 are configured as T1/PRI ports providing point-to-point T1connection
between the MAX and other devices. WAN port 3 is a drop/insert line. WAN ports 4 through 6
are covered because they are unused.
MAX 3000 E1/PRI
WAN ports 1 and 2 are configured as E1/PRI ports providing point-to-point E1connection
between the MAX and other devices. WAN ports 3 through 6 are covered because they are
unused.
Interfaces on expansion cards
AIM/BONDING
The DCE interfaces in Figure 1-9 on page 1-5 and Figure 1-10 on page 1-5 provide
AIM/BONDING inverse-multiplexing services to devices connected to them. (For details
about cables that connect to these ports, see “Serial host interface specifications” on
page C-19.)
ISDN BRI
ISDN BRI ports (Figure 1-5 on page 1-4) on network and terminal interface cards are a group
of either eight DTE or eight DCE ports providing point-to-point ISDN BRI connections
between the MAX and other devices. In the MAX manuals, these ports are called the Net/BRI
and Host/BRI ports for the DTE and DCE interfaces, respectively. From the point of view of
the MAX, pins 3 and 6 transmit on the Net/BRI interface and receive on the Host/BRI
interface. Pins 4 and 5 receive on the Net/BRI interface and transmit on the Host/BRI interface.
(For details about cables that connect to these ports, see “Interface specifications for ISDN
BRI” on page C-18.)
IDSL
The IDSL ports (Figure 1-6 on page 1-5) are a group of eight DCE ports providing
point-to-point IDSL connections between the MAX and other devices. An IDSL port has the
same pinouts as a Host/BRI port. (For further information, see “IDSL specifications” on
page C-40.)
Upgrading memory and compression modules
You can upgrade the MAX 3000 unit’s main memory (DRAM), nonvolatile (flash) memory,
and compression/encryption coprocessor by changing or adding modules. For information
about upgrading, see Appendix B, “Upgrading the MAX 3000.”
