PortMaster Communications Server        1


The PortMaster Communications Server is a high-speed network communication server designed to operate in a multiprotocol network environment. It provides shared network access to printers, modems, and other attached peripherals, as well as access to terminals, X terminals, and remote users using dial-up networking.

PortMaster Communications Server Product Line

 Table 1-1 gives product line information on the PortMaster Communications Server.  

Table 1-1 PortMaster Communications Servers

Model

Description

PM-2

Offers 10 asynchronous ports. Permits access to parallel devices (such as printers) via a parallel port.

PM-2E

 

Expandable server. Up to two expansion boards can be added for a total of up to 30 asynchronous ports or 10 asynchronous ports and 10 Basic Rate Interface (BRI) ports. Expansion boards are described in Table 1-2.

PM-2R

PM-2ER

 

The PM-2R and PM-2ER can extend networks over long distances using leased lines, Frame Relay, ISDN, or switched 56Kbps circuits. These models include a synchronous port that can be configured for RS-232 or V.35 signaling to provide WAN connectivity at speeds up to T1 (1.544Mbps) or E1 (2.048Mbps).

The PM-2ER is an expandable server. Up to two expansion boards can be added for a total of up to 20 asynchronous ports or 10 asynchronous ports and 5 BRI ports. Expansion boards are described in Table 1-2.

PM-25

Offers 25 asynchronous ports, consisting of one console port and three high-density 68-pin connectors, each of which support eight asynchronous serial devices.

PM-2i-U

PM-2i-ST

ISDN models. These servers each have 5 BRI channels providing, respectively, either a U interface with integrated NT1, or an S/T interface requiring an external NT1.

PM-2Ei-10I-U

PM-2Ei-10I-ST

Expandable ISDN models. These servers each have room for up to two expansion boards (5 BRI ports each), for a total of up to 15 BRI ports (30 B channels). Expansion boards are described in Table 1-2.

 Table 1-2 gives information on PortMaster Communications Server expansion boards.

Expansion Board

Description

MOD-2E-10A

MOD-2E-10B

This board provides 10 asynchronous ports
(S10 through S19).

This board provides 10 asynchronous ports
(S20 through S29).

MOD-10I-U

This board provides 5 BRI ports (10 B channels) and one high-density 10-pin RJ-45 connector supporting all five BRIs in one cable. This board provides an integrated network termination (NT1) device that attaches directly to the ISDN line; an external NT1 is not necessary.
U interface products are intended for use in the United States and Canada.

Revisions A and B of the MOD-10I-U board can be used only in the PortMaster 2E. Revision C or later boards can be used in any expandable PortMaster.

MOD-10I-ST

Offers 5 BRI ports (10 B channels). This board provides an S/T interface for countries that follow international ISDN standards.

 Figure 1-1 shows the front panel of the PortMaster Communications Server. The product name displayed on the figure applies to the PM-2 model; the model number varies for each unit.

PortMaster Software

Every PortMaster product comes with Lucent ComOS operating system software installed in nonvolatile RAM. This software is periodically updated; new releases are announced on the PortMaster mailing lists and are available by anonymous FTP from ftp://ftp.livingston.com.pub/le/. See "Subscribing to PortMaster Mailing Lists" on page xiv for information on mailing lists.

ComOS version 3.7.2 or later is recommended for all PortMaster models. Table 1-5 lists the earliest ComOS version that can be used with each PortMaster.
