3.3.21 TMS2 (Not for U.S.)

Introduction

The TMS2 board (trunk module S2M) provides 30 B-channels (ISDN voice channels) for Hicom 150 E OfficePro. These channels can be used fro the following:

S2m trunk connections (via NT)
S2M networking via S2M lines

You can use the Euro-ISDN CAS gateway (ECG) to support country-specific CAS protocols. The ECG is a protocol converter that converts the Euro-ISDN subset to channel-assiciated signaling (CAS). Refer to the installation instructions that come with each ECG for information on connecting the unit and supplying it with power.

Jumper Settings

The X300 or X302 jumpers are used to set the TMS2 interface for the connection of this interface to NT1. The following can be set:

Symmetrical line (120 ohms)
Use only pre-formed cables S30267-Z57-Axxx to guarantee problem-free operation (length = 6 m (not available in BRD), 10 m or 20 m).
Coaxial line (75 ohms)

S2M Trunk Connection

Table 2-8 on page 2-19 lists examles of the maximum cable lengths for connecting trunks.

Figure 3-69 S2M Trunk Connection (Not for U.S.)

Observe the following when connecting NTs using the S30267-Z57-Axxx cable:

Keep the cable from the NT to Hicom 150 E OfficePro as short as possible to ensure proper operation.
Hicom 150 E OfficePro must always be grounded (whether the line used by the network provider is copper or optical fiber). (See 1 TR 211 item 2.4, Protective Measures and Grounding.). The diameter of the earth conductor must be at least 2.5 mm2. Grounding the system using sheath wires is not sufficient. Keep the earth connection from the NT to Hicom 150 E-M as short as possible to ensure proper operation.
 
Caution 
In order to guarantee successful operation, you must ensure that the NT is grounded on the network provider side.  
Power feeding
The following information applies to systems that are supplied with power directly from the site electrical system (without uninterruptible power supply; (see Figure 3-70):
Use an optiset E local power supply (S30122-K5061-X1). A UAE 8/8 socket (L30460-X951-X = exposed, L30460-X952-X = concealed, L30460-X958-X1 = exposed/concealed) is required to connect the local power supply.
You must connect the external local power supply to the same site power phase as the system and the local power supply's plus pole to the system earth.
The following information applies to systems equipped with an uninterruptible power supply (see Figure 3-71):
The NT must be supplied with power using the -48 V from the PSUI/UPSM (15 W maximum; note the power requirements of the NTs). This ensures that the NTs will be supplied with power and the connected S2M lines will function in the event of a power failure.
Route the supply voltage through backplane connector X06 (pins 17 and 37 = -48 V). Do not use the supplied CABLU to connect the system and the MDFU. This energizes pair no. 15 (-48 V) of the splitting strip.
The CABLU is not supplied if the REAL board was ordered or is already being used (the parts supplied for the Trunk power failure transfer using REAL feature include the required CABLU).
