Features
The ASMi-31 short range modem supports full duplex transmission over
2-wire twisted pair unconditioned lines.
2-wire twisted pair unconditioned lines.
The ASMi-31 modem operates in pairs with either another standalone
modem, or as a card installed in the ASM-MN-214 hub.
modem, or as a card installed in the ASM-MN-214 hub.
A management channel transmitted in-band allows remote configuration for
the modem, real-time alerts on failures, and diagnostic testing. The line data
rate is selectable from 1.2 kbps up to 128 kbps and the line encoding is
2B1Q. ASMi-31 achieves an operating range up to 8 km (5 miles) over
24 AWG wire, independent of data rate.
The ASMi-31 modem is fully compatible with ASM-31 and SRM-31 and
works opposite MP-2100/HS-U module.
The ASMi-31 modem features automatic rate detection in external clock
mode for tail-end applications.

Control Signal Transfers
ASMi-31 supports end-to-end transfer of two control signals: DTR to DSR
and RTS to DCD, except for the V.35 interface or any other standard that
doesn't support this signal (such as X.21, G.703).

Interfaces
ASMi-31 supports the following interfaces: V.24/RS-232, V.35, X.21,
V.36/RS-449, RS-530, G.703 Codirectional, or built-in Ethernet bridge.

Diagnostics
ASMi-31 contains two diagnostic loops for complete diagnostics of both
local and remote modems:
ASMi-31 contains two diagnostic loops for complete diagnostics of both
local and remote modems:
•
Local analog loopback
•
Remote digital loopback
Both loopbacks are controlled via pins in the DTE interface and are
supported by their respective standards.
