common set of cards for traffic, radio interface, and management:
Traffic/Control Card (TCC)
Can be used in 1RU and 2RU chassis
Contains 2 x 1 GbE Ethernet combo interfaces (electrical or optical)
Radio Modem Cards (RMC)
RMC-E – Supports up to 4201 QAM (with ACM) and Header
De-Duplication. RMC-E also supports XPIC, with up to 4201 QAM
modulation.
The RMC-E has two variants. It can be ordered either as an RMC–only,
or as an RMC integrated with an STM1/OC3-RST interface.
Line Cards (LIC)
Ethernet – LIC-X-E4-Elec (4x GE), with 1 GbE combo interface and
3 GbE electrical (RJ-45) interfaces
Ethernet – LIC-X-E4-Opt (4x GE) with 1 GbE combo interface and 3 GbE
optical (SFP) interfaces
TDM – LIC-T16 (16x E1)
TDM – LIC-T155 (1x ch-STM-1)
TDM – LIC-STM1/OC3-RST
The 1RU chassis supports up to four high-power radios, with redundancy
