PAGE 41
System Installation 2.1.4 Introduction Choosing a Location for Your System The integrated access system requires a reasonably dust-free, static-free operating environment, such as a computer room. Adequate ventilation is also required at the site. Do not install the chassis in direct sunlight, which may increase the system’s operating temperature and affect its operation. Most of the system plug-in cards have highly sensitive components that could be damaged by static electricity.
PAGE 42
Model No. System Installation Running Head Introduction 2.1.4.2 Wall-Mount Installation Tips To mount the chassis on a wall, first obtain a piece of standard, marine-grade plywood (3/8 inch diameter, typical) and bolt it firmly to the desired mounting surface. This board must be long and wide enough to cover the entire chassis length and height. The surface must be able to support the total weight of the system (chassis plus plug-in cards). 2.1.4.

System Configuration and Operation Reinitializing the System When you remove and replace most card types, the NVRAM remembers the old card’s settings. If the same kind of new card is inserted in the slot, you do not need to reprogram the settings. However, if you replace a card with a different type of card, the system lets you delete the old card, so that you can program new parameter settings for the new card (see the Accept function described earlier in this chapter).

Model WAN CardNo. Running Head WAN Card Descriptions 6.2.6.2 Module Installation For DSX or CEPT operation, you must install one of these modules on the associated WAN card before inserting those cards into the system chassis. Figure 6-1 shows the locations of the DSX/CEPT modules on a WAN card. One module is required per WAN port. If your system has a T1 link (DSX) and an E1 link (CEPT), you will need two DSX/CEPT modules. First, install a DSX/CEPT module in the slot reserved for WAN port 1-1.

Running Head WAN Card Descriptions Model WAN CardNo. For 75-ohm unbalanced E1, set the adapter panel jumpers to UNBAL in one location only, and set them to BAL in all other cases. When multiple DSX/CEPT modules with jumpers are installed, the unbalanced jumper should be set on the module closest to the E1 line. When the adapter panel is present, it is considered the unit closest to the E1 line.

WAN Card 6.2.9 WAN Card User Screens and Settings Installing the WAN Cards After installing the proper modules on the WAN cards, insert the WAN cards into the system chassis. Each system can have up to four WAN cards, which go into slots W1 through W4. For a system with redundant WAN cards, always insert a WAN-R card into slot W4. If you install the WAN-R card into any other WAN card slot, it will work as a regular WAN card (not as a redundant card).
PAGE 214
Model WAN CardNo. Running Head WAN Card User Screens and Settings The headers of all WAN card screens show the types of modules installed on those cards. The above example shows a WAN DUAL card with a CSU module on port 1 and a DSX/CEPT module configured for T1 DSX operation on port 2. This card is installed in WAN card slot W1 of the system. Its screen header designation is therefore W1 CSU+DSX. The DSX/CEPT and HDSL modules also have identical parameters.

Running Head Model No. SR TS overlapping. The subrate circuit assigned does not allow enough space for a previously assigned circuit on the same subrate time slot. For example, if you have a 19.2 kbps device on subrate time slot 1 in b-5 framing, you cannot assign another 19.2 kbps circuit to subrate time slot 2, because the circuit on 1 actually occupies subrate time slots 1 and 2. You must therefore assign that other circuit to subrate time slot 3 or 4. Switch request sent to card.
