Analog Station Module (ASM)
-
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
