# 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.

`Table 1-2 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.

1)Ports S10 through 19 are ISDN B channels if a MOD-10I-U or MOD-10I-ST board is placed in the first expansion slot. Ports S20 through 29 are ISDN B channels if a MOD-10I-U or MOD-10I-ST board is placed in the second expansion slot.

2)A single asynchronous serial port (S0) is provided, as well as three high-density 68-pin connectors, each of which supports eight asynchronous serial devices.

## 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.

To configure the PortMaster, you can use either of the following:

- Lucent's Command Line Interface. If you are using the command line interface to configure the PortMaster Communications Server, refer to the Command Line Administrator's Guide and the Configuration Guide for PortMaster Products for instructions.

- Lucent's PMconsole Software. PMconsole guides you through configuration using a simple graphical user interface (GUI). It is available for Windows 95, Windows NT 4.0 or later, and for many versions of UNIX. You can install PMconsole from the PortMaster Software CD or from the Lucent Remote Access FTP site.

  Refer to the PMconsole for Windows Administrator's Guide for configuration instructions.

Note ¯ You must use the command line interface to configure certain ComOS features such as the Open Shortest Path First (OSPF) protocol on the PortMaster Communications Server.
