Dual Serial and Quad Serial – C/CE Expansion Modules
The Dual Serial expansion module contains a single dual serial WAN port (two serial ports located
on one high density connector). The Quad Serial – C and Quad Serial – CE expansion modules
each contain two dual serial WAN ports. In addition, the Quad Serial – C expansion module
includes compression, and the Quad Serial – CE expansion module includes compression and
encryption, for each WAN port.
