TCAS-2 and TCASR-2 (for selected countries only) 
 
NOTE: Danger of damage to property due to surge voltage. The required lightning protection measures must be taken for this board, see Section 2.1.2 "Lightning Protection".  

Introduction  
The following cards - one per system - can be used for V5.0 SMR -10 and later to support country-specific CAS (Channel Associated Signaling) protocols:
 •   TCAS-2 (S30810-Q2945-X) in HiPath 3550
 •   TCASR-2 (S30810-K2945-X) in HiPath 3500
Please note that the cards listed can only be used in slots 7 and 9.
Each of the cards features two E1-CAS interfaces, which together support up to 60 B channels. Since HiPath 3550 and HiPath 3500 each support a maximum of 30 B channels, a total of up to 30 B channels can be used per card.
Direct connection to the MINI BNC connectors on each card is only possible for coaxial trunks (75 ohms). An external impedance converter (F31505-E1-A146) must be used for symmetrical trunks (120 ohms).
TCAS-2 and TCASR-2 function as converters, which convert the Euro-ISDN protocol on an S2M link to the Channel Associated Signaling protocol CAS. In contrast to the predecessor TMCAS board, TCAS-2 and TCASR-2 communicate directly with the central control in the system. All signaling and data traffic goes through TCAS-2 and TCASR-2. Unlike TMCAS, connection to an S2M board is therefore not required.

Seven-segment display  
The card's software status can be ascertained on the basis of the seven-segment display. For this a distinction is made between the following boot phases:
 •   U-boot (firmware) states

Modem (optional)  
 Figure 3-91   TCAS-2, TCASR-2 (for selected countries only) - Optional Modem
 
The analog modem (modem kit F31505-E1-A147) is an optional subboard for the TCAS-2 and TCASR-2 cards, which is plugged into the X20 and X21 ports. This facilitates remote administration of the CAS protocol converter on the TCAS-2 and TCASR-2 cards (see Page 3-259).

Administration of the CAS protocol converter  
A separate tool, the CAS Manager, is used to download the software and administer the TCAS-2 and TCASR-2. The CAS Manager software is stored on a CD supplied with the card. For information on how to install the CAS Manager software on the Service PC, refer to the readme file.
The following options are available for accessing the cards:
 •   Via the V.24 interface (9-pin MINI DIN jack X803) and the connection cable C39195-A9700-B532.
 •   Via the Ethernet (10/100BaseT) interface (RJ45 jack X804).
 •   Via the optional analog modem (modem kit F31505-E1-A147). In this case, you will need to establish a connection from the analog modem (RJ45 jack X805) to a free port in an analog subscriber line module via the RJ45 cable C39195-Z7208-A10 supplied with the modem kit (see Figure 3-93).

Assigning the CAS cable  
The following options are available for connecting network terminators (NT), multiplexers (MUX) or modems to the TCAS-2 and TCASR-2 cards (MINI BNC connections):
 •   Coaxial trunk (75 ohms), length = 10 m

 •   Symmetrical trunk (120 ohms)
    The impedance converter F31505-E1-A146 must be used for connecting to a symmetrical trunk.

 •   CAS cable shield contacts
    To ensure sufficient electromagnetic shielding (according to EN 55022), both shielded CAS cables must be contacted at the appropriate points on the HiPath 3550/HiPath 3350.
    Procedure:
    Fix the cable shielding (B) for both CAS cables (A) via cable binder (C) to the T tongue (D) of the housing, so a continuously conductive contact is created between the conductive tape on the cable shielding and the housing (see figure).
