Port
Connections The rear of the PRISM 3111/3112, contains up to eight port connections as shown
in Figure 2-1: LAN, SLIP, SUPV, optional T1 DTE, NET, DBU, Data Port 1, and
an optional Data Port 2
LAN The PRISM 3111/3112 can be equipped with an internal Ethernet or Token Ring
network interface card (NIC) for connection into a local area network (LAN). The
connection is an 8-pin modular jack on the rear of the unit labeled LAN. The NIC
can be installed without changing the rear panel. The LAN port will not function
unless the optional NIC is installed.
The Simple Network Management Protocol (SNMP) agent can be programmed to
take advantage of the centralized status monitoring and alarm reporting capability
of SNMP managed networks. This unit is also compatible with the TXPORT
8100A Site Controller as a remote or far-end element. The 8100A is used to
manage TXPORT network access products.
Ethernet
The Ethernet interface complies with standard twisted pair, 10BASE-T
requirements. Table 2-1 displays the pinout assignments for the 8 -pin modular
jack when configured for an Ethernet connection.
Configure the LAN interface before you connect the PRISM 3111/3112 to the LAN.
Refer to the SNMP Configuration section on page 39 (front panel interface) or page
69 (terminal interface) for specific information.
Token Ring
The Token Ring interface is designed to operate on both 4 and 16 Mbps networks
and complies with standard unshielded twisted pair requirements. The Token Ring
interface is Type 3. Table 2-2 displays the pinout assignments for the 8 -pin
modular jack when configured for a Token Ring connection.
