Signaling service processing platform

ETI Boards

In the ETI board names, A and B represent the version, and digits 0, 1, and 2 represent the board configuration models. Boards with the same basic functions but different configurations are named separately for identification.
Figure 8 and Figure 9 show the location of service interfaces on various ETI boards. Table 3 describes the specifications of service interfaces on various ETI boards.

Board	Physical Port	Function	Description	Quantity
ETIA0	E1/T1 port	It is used for TDM signaling access.	Each ETIA0 board provides two DB-78 ports (2 x 16 E1/T1 ports).	2
	8 kHz clock port	It provides external clock input.	Each board provides two RJ-45 clock ports.	2
ETIA2	E1/T1 port	It is used for TDM signaling access.	Each ETIA2 board provides one DB-78 port (1 x 16 E1/T1 ports).	1
	GE port	It is an Ethernet port used for communication with other devices.	The ports are RJ-45 ports that support 10/100/1000 Mbit/s Base-T auto-negotiation.	2
	8 kHz clock port	It provides external clock input.	An ETIA2 board provides two RJ-45 clock ports.	2
