IEN 4000
The IEN 4000 is an eight-slot, branch or regional concentrator chassis. Each IEN 4000
chassis supports a maximum of eight port processors. The chassis can be bus connected
with up to two additional IEN 4000 chassis for a 16, 24, or 32-slot configuration.
The IEN 4000 chassis uses hot swappable 110/220VAC auto sensing power supplies. The
IEN 4000 chassis comes standard with a single power supply and has the option of
installing a redundant power supply.
The IEN 4000 chassis come standard with a single power supply and a second redundant
power supply. When IEN 4000s chassis are bus connected, the standard and high speed
bus are extended.
The IEN 4000 chassis allows different technologies to come together on a centrally
managed platform, including SNA/SDLC, ASYNC, BSC 3270, IP and IPX. It also integrates
multiple traffic types over a single WAN interface, such as ISDN, X.25, or frame relay. The
IEN 4000 chassis comes with the ability to add an asynchronous transfer mode (ATM) T1 or
OC3 interface to utilize the performance advances of cell relay.
Digital or analog voice interfaces can be used to provide compressed or channelized voice
capability. Each voice port processor supports four, 2-wire or two, 4-wire voice channels
per port processor for a maximum of 48 voice channels for each IEN 4000 chassis.
