System Software Control
Features
- Standard compliant TL-1
Command Line Interface
- Auto-provisioning of all
modules during installation and initialization
- Upon insertion of a
replacement module:
Automated Hardware and Software compatibility checks
Automated Software download of current module software
Auto-provisioning from current provisioning database
- Inventory in software:
Input reference source
Output port assignment
Inventory CLEI and Mfg Serial Number in software to help in field
servicing and PCN administration
Modular Redundancy in
Hardware
- Dual Power Inputs &
Power Supplies
- Up to 5 References
Inputs
- Inputs bridge to both
IOP Modules
- Dual IOP’s (ST-2 or
ST-3E)
- Paired Output Modules
for 1 to 1 Protection
Microprocessor Control &
Memory Features
- Top level IntelTM
microprocessors on COM and both IOP modules
- System Databases stored
on the COM module are backed up on BOTH IOP’s
- Output Module on-board
microprocessors enable management to each output port
Oscillator Options
- Standard Quartz ST-3E &
Rubidium ST-2
- Optional Stratum 2 High
Precision Double Oven Quartz Oscillator (DOCXO) - ST- 2
performance at lower cost
System Communications
Interfaces
- Local craft interfaces—2
( 1 front panel)
- TCP / IP Local Area
Network interface via RJ-45
Integrated GPS Receiver
The US5GM is designed to
integrate GPS receiver. This arrangement optimizes rack bay
utilization by eliminating separately mounted GPS unit. The
GPS reference is independent of other input capacity meaning
all other inputs are still
available for selection or for monitor only operation.
Alarm Reporting Modes
- Module Status and Alarm
LED’s
- 6 Contact Closure
Relays—Local & Remote
- TL-1 Autonomous Output
Messaging
- 16 Discrete Alarm Input

module PM data
Clock modules (IOP
modules)
Based on
Rubidium or quartz oscillator, possibility of mixed
configuration
Dual redundant clock modules
Clock performance : ITU-T G.812 type 1 & 2 or ANSI T1.101
type ST2 or ST3E
