ASM-40 synchronous short range modem from RAD
ASM-40, a synchronous short range modem, operates in full duplex over 4-wire lines or BNC coaxial cable. The RAD ASM-40 modem extends data transmission range for up to 1.75 km (1 mile). ASM-40 employs HDB3, AMI or B8ZS line coding in compliance with the G.703 standard requirements. ASM-40 supports a wide range of serial and Ethernet interfaces, including V.24, V.35, X.21, V.36, RS-530,
G.703-HDB3, G.703 Codirectional, IR-ETH (Ethernet bridge), Ethernet bridge, Ethernet bridge with VLAN support, Ethernet/Fast Ethernet bridge with VLAN support, IP router.
The RAD ASM-40 modem line rates support different data rates, which enables ASM-40 to be used as a rate converter:
2048 kbps 32, 64, 128, 256, 512, 1024 and 2048 kbps
1536 kbps 192, 384, 768 and 1536 kbps
1544 kbps 1544 kbps
1920 kbps 1920 kbps.
ASM-40 operation complies with the AUSTEL (A95/76A/0020), TUV (E9471050.01), BABT and NET-1 requirements.
Transmit and receive timing can be provided internally, or derived externally from the data terminal or receive signal. Internal FIFOs provide jitter attenuation or phase difference correction either from the incoming analog signal (line side) or from the external clock on the DTE side.
ASM-40 has comprehensive diagnostics capabilities that including:
Local analog, remote digital and local digital loopbacks in compliance with ITU V.54 requirements
Built-in pattern generator and tester in compliance with ITU V.52 requirements.
ASM-40 is also available as a plug-in card for RADs ASM-MN-214, 19-inch card cage.
