NAMC-xE1

Basically, the NAMC-8E1/T1 provides 8 E1/T1 interfaces towards the front panel without further processing resources. If equipped with a mezzanine card, the number of line interfaces of the then so-called NAMC-16E1/T1 board  rises up to 16.

The NAMC-xE1/T1 is designed for (tele-)communication applications with a need for a high aggregation of multiple E1/T1 interfaces combined with access to switched networks based on high bandwidth Ethernet. The TDM-to-I-TDM converter provided by the FPGA connects the on-board E1/T1 interfaces with a Gigabit Ethernet port for system interconnects (I-TDM).
