ISDN RAS on 128 bearer channels
V5 to V5 Gateway (V5.1/V5.2, V5.2/V5.1) V5 Engine-4 E1
E1/T1/J1 frame captures for monitoring ISDN/CAS to V5 gateways
SS7 MTP1 and MTP2
NODCOM QUAD E1/T1 PMCis an active Signalling engine (ISDN, V5, SS7) with passive HDLC capability over 128 channels. A Powerful DSP option is available for on-board Media processing.

QUAD E1/T1 PMC ISDN SIGNALLING ENGINE SOFTWARE ARCHITECTURE
The software architecture is based on the NODCOM architecture which is close to the ISO/CCITT X.200 model.
All protocol entities are managed as isolated objects communicating through a datagram message passing scheme. The message passing is based on FIFO queue communications. The entities of the system are housed in processes (one or several entities in one process) managed by an AMX 68000 (KADAK) real-time multi-tasking kernel. When the origination and destination entities are in the same process the message passing is done through an internal FIFO without need of AMX scheduling. When the two entities are in different processes the message passing is done using AMX message exchange management.
The software code is downloaded through the serial port to Flash memories.
The product management: configuration, audit, log is done through an UART serial port or through the Dual-port memory and could be done through the network using a Remote Control function.
The "protocol entity architecture" figure describes the different protocol stacks and the communication between the entities of the system. The following stacks and entities are in the system:
. System management SM . Signalling stack:
MPH-D physical layer management and framer control PH-D physical HDLC D channel protocol
MPH-B physical layer management PH-B physical HDLC B channel protocol MDL data link layer management DL data link protocol (LAPD,V.120) MNS network signalling management NS network signalling protocol
CC call control protocol for voice and data support DTE-INT DTE interface using "AT" command set RC remote control entity
CAS signaling . Optional User data stack:
DPM Dual-port memory driver MX25 X.25 layer management X25 X.25 PLP packet layer protocol DTE-INT DTE PAD (X.3, X.28, X.29) protocol . API entities :
