1-4 Introducing the ELMo 120 Multiplexer
Revision 2.01 ELMo 120 Multiplexer Installation and Maintenance Guide 08-01023-01
ELMo 120 Multiplexer components
This section describes the function and purpose of each of the ELMo 120
Multiplexer component cards.
Power card
The Power card converts the -48 V dc power feed to the power levels used by
the ELMo 120 Multiplexer components.
Ethernet 10/100Base-T Switch card
The Ethernet 10/100Base-T switch card collects the Ethernet traffic generated
by the ELMo 120 Multiplexer modem cards and passes it to the local data
network.
Switch card ports
The Switch card has two "up-link" Ethernet ports and one "interconnect" port
on the front faceplate of the card. The top two up-link ports are autosensing
Ethernet 10/100Base-T ports (uncrossed) that can be used to connect the
ELMo 120 Multiplexer shelf to the data network. The bottom Ethernet
10Base-T port is a crossed port that can be used to interconnect or "stack"
connections between ELMo shelves in a multi-shelf bay.
Modem cards
One ELMo 120 Multiplexer shelf can support up to 10 Modem cards. Each
ELMo 120 Multiplexer modem card controls 12 Elite modems, directing data
traffic flow between the Elite modems and the data network.
Modem card and port numbering
ELMo 120 Multiplexer Modem cards are numbered 1-10, from left to right
(when viewed from the front). The 12 logical ports on each modem card are
numbered 0-11. Each logical port on a Modem card corresponds to one Elite
modem/CPE phone line.
Note: The ELMo 120 Modem card ports are provisioned using the Port
Manager application on the YesWare Server. For information on how to
provision ELMo120 Modem card ports, see the YesWare Applications
User’s Guide.
