-
The Analog Station Module is compatible with
Modular ICS products with fiber nterface capabilities.
-
Each ASM can support 8 analog devices (data
or voice) with speeds up to and
including 33.6 Kbps. (Note: the maximum data transmission rate is
subject to
the quality of the end-to-end channel and cannot be guaranteed.)
-
Each ASM has 3 connectors: one DS-30 fiber
link for daisy-chaining, and one
50-pin male amphenol connector that provides connections for up to 8
analog
devices.
-
The ASM connects to a Fiber Expansion
Cartridge on the core Modular ICS
with a DS-30 fiber cable. Either a 2 or 6 ports Fiber Expansion
Cartridge may
be used.
-
The second DS-30 jack on the ASM may be used
to daisy-chain a second ASM
to the first. A maximum of two ASMs, providing a total of 16 analog
ports, can
be connected through a single DS-30 port on an Expansion Cartridge.
-
The ASM is approximately 1.5 times wider than
the Fiber Station Module.
Two versions of the ASM are available:
— Standard Analog Station Module (ASM) M0x8A
— Analog Station Module with Message Waiting Indication (ASM with
MWI)
M0x8M
-
The ASM with MWI supports visual message
indication (on 2500 sets with a
message lamp provided) or stuttered dial tone (when the handset is
lifted).
(Note: The standards ASM does not provide visual message waiting
indication
but can be configured to provide a stuttered dial tone if connected
to a Modular
ICS with DR 1.1 software or later. The standard ASM cannot be
upgraded to an
ASM with MWI.)
-
The standard ASM is compatible with all
Modular ICS software releases. The
ASM with MWI is compatible only with DR 1.1 and XC 1.1 software or
later.
The ASM and the ASM with MWI may be used in combination with each
other
and/or with existing ATA-2s, allowing for customized analog
solutions. All
features currently supported on the ATA-2 are supported by both
versions of the
Analog Station Module.
-
The maximum loop length for any On Premise
analog station is 4,000 feet. Off
Premise Extensions (OPX) are not supported from the ASM. The
existing ATA-
2 devices will still be used to support OPX extensions.
Note:
CLASS/CMS capabilities and Disconnect Supervision are not supported
on the Analog Station Module. This is consistent with ATA- 2
functionality.
For analog connections requiring Disconnect Supervision, a Voice
Mail
Interface (VMI) Unit is required
