NAMC-xE1/T1 and NAMC-xE3/T3

Advanced Mezzanine Card (AMC) with 8-, 16-E1/T1 or 4-E3/T3 interfaces

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

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

The NAMC-xE1/T1 is dedicated for (tele-)communication applications with extensive need for a high aggregation of multiple E1/T1 interfaces combined with access to switched networks based on high bandwidth Ethernet.

The NAMC-xE1/T1 is used for distributing signaling and payload data to DSP or CPU based processor resources within a MTCA or ATCA system.

The NAMC-xE3/T3 offers 4-E3/T3 interfaces. T3 handles a bandwidth of 44.736 Mbit/s or 672 channels and E3 supports data transmissions of 34.368 Mbit/s or 512, a higher data speed compared with E1 (2.048 Mbit/s - 32 channels) or T1 (1.544 Mbit/s - 24 channels).
