ETS2 overview

1 ETS2 overviewThis document describes the ETS2 exchange terminal plug-in unit.

Purpose of ETS2 unitThe ETS2 is an exchange terminal unit. It has two STM-1/OC-3 optical interfaces and is responsible for framing, mapping and multiplexing of two times sixty-three 2.048 Mbit/s or two times eighty-four 1.544 Mbit/s tributaries into SDH STM-1 frame and vice versa. In SONET OC-3 mode ETS2 is responsible for framing, mapping and multiplexing of two times eighty-four 1.544 Mbit/s tributaries into SONET STS-3 frame and vice versa. The ETS2 can be installed in dedicated GT4C-A and GT6C-A cartridges.

The ETS2 provides the following:

• two duplicated STM-1/OC-3 optical interfaces • two duplicated Serial Broadband Interfaces (SBI) with a bit rate of 655 Mbit/s each

connected to the GSW2KB • 8 Mbit/s TDM lines for HDLC/LAPD • two IEEE 802.3/Ethernet interfaces with bit rate of 10/100 Mbps that can be used to

handle same functions as the HDLC/LAPD link.

Operating environment of ETS2 unitThe ETS2 plug-in unit is connected to two external STM-1/OC-3 optical interfaces. The unit is connected to the switching network with two redundant SBI interfaces. The main-tenance of ETS2 is handled with an LAPD link, which is connected by the separate 8 Mbit/s TDM-lines or 100 Mbps Ethernet interfaces.

Operating voltages required by the units are formed with an on board integrated power unit from an external -48 V voltage.

The following figures display the operating environments of the ETS2 plug-in unit.

Capacity and performance of ETS2

2 Capacity and performance of ETS2The capacity of the ETS2 is two SDH STM-1/Sonet OC-3 interfaces with bit rate of 155,52 Mbit/s each. They have been duplicated for redundancy. The optical interfaces are provided by hot-pluggable SFP modules, which are not part of the structure of the ETS2 plug-in unit.

The ETS2 has

• MPC8280 PowerQUICC II HIP7 processor • 128 MByte SDRAM main memory at 100 MHz • 8 MByte Boot Flash

• two duplicated SBI interfaces with a bit rate or 655 Mbit/s each • two duplicated 8 Mbit/s TDM lines, from which 8x or 16x64 kbit/s used for single

unit's HDLC/LAPD link • two IEEE 802.3/Ethernet interfaces with bit rate of 10/100 Mbps.

3 Structure of ETS2

3.1 Mechanical structure of ETS2 plug-in unitETS2 plug-in unitThe ETS2 plug-in units consist of a single printed wiring board (PWB). The dimensions of the PWB are 233.35 x 222.3 mm. The thickness of the PWB is 1.6 mm and spacing in the cartridge is 4T (20.32 mm). There are eight SFP connectors in the front panel of the plug-in unit. There are also three leds on the front panel: one bicolour and two single-colour leds.

The unit connects to the backplane with 5-row Hard Metric Z-pack female connectors. The connectors are two AB-type female connectors (J1 and J4) and a 22-pin B-type female connector (J2).

3.2 Logical structure of ETS2 plug-in unitThe following block diagram of the ETS2 plug-in unit illustrates the logical structure (including possible loop interfaces).

3.3.1 External interfaces

STM-1/OC-3 InterfaceThe ETS2 has two redundant optical STM-1/OC-3 interfaces on the front panel (total of four interfaces), which are implemented using SFP transceivers. The SFP transceivers are not part of the structure of the ETS2 plug-in unit.

3.3.2 Intra interfaces

Serial Broadband InterfaceTwo 2N redundant SBI interfaces (total of four SFP connectors) are located on front plane. The SBI interface is used for connecting STM-1/OC-3 traffic of ETS2 plug-in unit to group switch.

Serial Control Bus InterfaceFour internal TDM lines are connected to the backplane. Two of these TDMs are con-nected to active GSW and two are connected to redundant GSW.

Ethernet InterfaceThere are two 10/100 Mbps Ethernet interfaces in the plug-in unit. The Ethernet inter-faces are accessible through a backplane.

LED indicatorThe front panel of the ETS2 plug-in units has one bicolour (red and orange) alarm LED indicator and two single-colour (one red, one green) LED indicators.

The green LED (OPR) is lit when at least one of the unit's STM-1/OC-3 interfaces is active.

The following functions are defined for the red LED (ALARM):

1. If the incoming synchronization signals of the unit are faulty2. If power failure occurs

The bicolour LED (Tx/Rx FAIL) indicates errors in STM-1 / OC-3 interfaces. The follow-ing functions are defined for it:

1. If there are no alarms or errors, the LED is off.2. If there are errors in TX direction, the LED is on (red colour)
