NAMC-xE1/T1 with 8 or 16 E1/T1, or 4 E3/T3 interfaces

AdvancedMC (AMC) line interface card for MicroTCA (uTCA, MTCA) or AdvancedTCA (ATCA) systems

The NAMC-xE1/T1 is an Advanced Mezzanine Card (AdvancedMC or AMC) in single width, compact-, mid- or full-size format providing up to 16 E1/T1 interfaces for next generation systems based on the MicroTCA (MTCA) and ATCA standards.

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.

This add-in card is used for distributing signaling (i.e. ISDN or SS7) and payload data to DSP or CPU based processor resources within a MTCA or ATCA system.

The TDM-to-I-TDM converter connects the on-board E1/T1 interfaces with a Gigabit Ethernet port for system interconnects (I-TDM).
