3.3.23 TS2 (Not for U.S.)

Introduction

The TS2 board (trunk module S2M) for OfficeCom connects the system to an NT1 (network transfer point) via a symmetrical line (four-wire, twisted-pair cable) or a coaxial line for the simultaneous transfer of up to 30 B channels (ISDN voice channels).

The total transmission speed including signalling and synchronization is 2,048 Mbit/s.

Only one TS2 board allowed (primary multiplex access)
For slot 7 or 9 only (Rel. 2.0 or later)
The maximum cable length depends on the quality of the cable used and its signal attenuation (max. 6 dB).
 
Use shielded cables only to guarantee proper operation.  

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

Interfaces

Figure 3-76 TS2-Interfaces (S30810-Q2913-X) (Not for U.S.)

Symmetrical Line (120 ohms)

The 120 ohm-variant is preset in the factory (jumper setting, refer to Table 3-74 on page 3-176). Connect the shielded cable to the X2 connector using an 8-pin Wieland terminal.

Table 3-73 TS2 Interface Assignments for Symmetrical Lines (Not for U.S.)

-48V (NT1 feeding) 
GNDA (NT1 feeding)

Coaxial Line (75 ohms)

Connect the coaxial line to the X2 connector using the 8-pin Wieland terminal. Adjust the jumpers on plug connectors X100 to X102 as shown in the Jumper Settings table.

Note: Use the connection kits listed on page 3-179 for NT connections in Spain and Portugal.

Jumper Settings

The TS2 interface setting for connecting to the NT1 can be selected using jumpers X100 to X102. Use the jumpers to set:

Symmetrical lines (120 ohms).
Cable C39195-A7608-C1 (10 m long) is shipped with the TS2 board. Cable C39195-A7608-C2 (20 m long) is available for greater distances. To ensure proper operation, use only these cables.
Coaxial lines (75 ohms).

S2M Trunk Connection

Figure 3-77 S2M Trunk Connection (Not for U.S.)

Observe the following when connecting NTs using cable C39195-A7608-Cx:

Keep the cable from the NT to Hicom 150 E OfficeCom as short as possible to ensure proper operation.
 
DANGER 
No ground connection may be made between Hicom 150 E OfficeCom and the NT. Do not connect the shields on cable C39195-A7608-Cx on the OfficeCom side or the NT side.  
Feeding
The following applies to systems that are fed exclusively from the site electrical system without USVC (see Figure 3-78):
Use a local power supply (such as S30122-K5061-X).
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 applies to systems that have an uninterruptible power supply (see Figure 3-71):
The NT must be fed via the -48 V from the PSUI/UPSM (15 W maximum; note the NT power requirement). This ensures that the NT will be supplied with power and the connected S2M will function in the event of a power failure.

Cable Set for NT Connections (Spain and Portugal Only)

Set the jumpers on pin connectors X100 to X102 to "symmetrical line (120 ohms)" as shown in the "Jumper Settings" table (page 3-151).
