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

Table 1-3 shows the available ports on each PortMaster Communications Server model. Table 1-4 on page 1-4 shows how to upgrade your PortMaster Communication Server. Physical specifications are listed in Appendix B.
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.

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.
|PM-2||Any ComOS release can be used.|
|PM-2E||Any ComOS release can be used.|
|MOD-2E||Any ComOS release can be used.|
To configure the PortMaster, you can use either of the following:
