3. OPTION MODULES
The ATLAS 550 has 25 option modules:
• T1/PRI Network Interface Module (P/N 1200307L1)
• E1/PRA Network Interface Module (P/N 1200308L1)
• Modem Management Network Module (P/N 1200341L1)
• BRI DBU Network Interface Module (P/N 1200327L1)
• Dual Nx 56/64 Option Module (P/N 1200311L1)
• Dual USSI Option Module (P/N 1200754L1)
• Dual/Quad T1/PRI Option Module (P/N 1200314L1/1200755L1))
• Quad Basic Rate ISDN (U-Interface) Option Module (P/N1200315L1)
• Quad Basic Rate ISDN (S/T-Interface) Option Module (P/N1200764L1)
• Octal/Quad FXS Option Module (P/N 1200309L1/1200328L1)
• Octal/Quad FXO Option Module (P/N 1200310L1/1200329L1)
• Octal E&M Option Module (P/N 1200313L1)
• Octal Ethernet Switch Option Module (P/N 1200766L1)
• Resource Host Module (P/N 1200324L1)
• 4,8,16,24 Channel Voice Compression Resource Modules (P/N 1200312Lx)
• 32 Channel ADPCM Resource Module (P/N 1200752L1)
• Nx 56/64 BONDing Resource Module (P/N 1200326L1)
• Legacy Data Option Module (P/N 1200342L1)
• NxT1 HSSI/V.35 Option Module (P/N 1200346L2)
Each option module is hot-swappable with configuration restored upon replacement.
Each option module has a variety of performance and alarm status information. Several features of each
module are user-configurable, although default values reflect the most common configurations. All option
modules contain an extensive self-test as well as tests designed for the technology they incorporate.
T1/PRI Network Interface Module (P/N 1200307L1)
The T1/PRI Network Interface Module provides one channelized T1 or PRI interface. This interface
operates in DS-1 or DSX-1 mode and can deliver timing for the system. The ATLAS 550 domestic system
(P/N 1200305L1) ships with one installed T1/PRI Network Interface Module.
Replacing an option module with a different module type will result in configuration loss.
