The TP-1610 is composed of one or two identical media gateways modules: Gateway-1 and Gateway-2, each containing 240 DSP channels. These media gateways are fully independent, each gateway having its own MAC (Media Access Control) and IP addresses and LED indicators. The TP-1610 board is supplied with a rear I/O configuration in which both PSTN trunks and Ethernet interface are located on a passive rear I/O module (for information on the RTM, refer to

Section 2.4 on page 24).
