AMS16 & AMS4

AMS4 and AMS16 chassis enable communication card concentration for all kind of telecoms media in a 19'' rack with various options of density, power supply redundancy and network management

Chassis 19'' modem SNMP

AMS4 is a 19''/1U chassis to host 4x modem cards with one sfixed power supply converter

chassis 19'' modem

AMS16 is a 19''/4U chassis to host up to 16x modem cards, one SNMP management card, and one or two power converters with redundancy, load sharing and mixed 110/230 Vac and 48 Vdc inputs.

Communication cards can be inserted and extracted during operation but no service interruption on other cards.

CFIP-L management card takes a separate slot in the chassis. It performs modem card inventory, configuration and monitoring. It forwards event and alarm notifications from modem cards and power supply modules to the network management system. This SNMP management card is particularly interesting for modem cards that do not provide any Ethernet / IP connection (dial up modems, ISDN adapters, simple E1/T1 converters). A graphical MIB file is provided for the SNMP manager.

AMS4 and AMS16 chassis can host the following communication cards:

  • 2885P : modem FAX for dial up and leased line, V21-V34
  • 6434 : ISDN adapter with V21-V34 and Fax modem
  • CV-xxxx : E1/T1 interface converter / CSU with serial and ISDN ports
  • CV200-TTX-R : E1/T1 interface converter / CSU with Ethernet port
  • SpeederLan-Bis : multi pairs Ethernet First Mile SHDSL-Bis access
  • FO-xxxx : fiber optic modem with E1/T1, E3/T3, ISDN, serial, and Ethernet interfaces


  • 4 slots for modem cards
  • 110/230 Vac or 48 Vdc power input
  • Size: 19''/1U - 440 x 315 x 44 mm


  • 16 slots for communication cards
  • 2 slots for power supply modules
  • 1 slot for the CFIP-L SNMP management card
  • PS16-U / PS16 : 110 / 230 Vac - 100 W power module
  • PS3E : 48 Vdc / 100 W power module
  • CFIP-L : SNMP management card
  • Size: 19''/4U - 482 x 343 x 178 mm
