All models include one asynchronous port, and one synchronous port that can be configured for RS-232 or V.35 signalling to provide WAN connectivity at speeds up to T1 (1.544Mb/s) or E1 (2.048Mb/s). The IRX-112 also has a second synchronous port that can operate up to 64K speeds. The IRX-114 has two T1/E1 synchronous ports and two 64K synchronous ports.

The IRX comes with lifetime software support and a one-year hardware warranty.

 Figure 1-1 shows the front panel of the IRX-114. All models have a similar form factor. Table 1-1 shows the available ports on each model.

Product	Ethernet	async	sync T1	sync 64k
IRX-111	ether0	s0	s1
IRX-112	ether0	s0	s1	s2
IRX-114	ether0	s0	s1,3	s2,4
IRX-211	ether0-1	s0	s1

The IRX-111 can be upgraded to an IRX-112 by adding a MOD-IRX-1 board, or upgraded to an IRX-114 by adding a MOD-IRX-3 board. The IRX-112 can be upgraded to an IRX-114 by removing the MOD-IRX-1 board and replacing it with a MOD-IRX-3 board.
