Multiplexers ISDN

E141  - Smart ISDN access switch and TDM

E201 - Smart ISDN access switch and TDM

E800 - 8 port E1 cross-connect

The access units of the E-Series are designed to deliver bundled services covering ISDN, Internet access and Legacy data services.

They interface on E1 uplink lines that contain FPRI and FE1.

The E800 can connect to several access units and cross-connect the different E1 data services into a single E1 trunk, while handling the different fractional PRI lines on a single PRI interface.

The E201 and E141 have a universal serial port,  which by means of different interface modules can deliver V.35, V.36 and X.21.
