14 Safety instructions

Before lifting or installing a component:

•

Ensure that the planned location and the route to that location are free of obstacles and debris.

•

Get help with heavy components or components that are to be placed in the upper section of a rack.

Power supply cables

The power supply cables must be no longer then 4.5 m in length and must have attachment plugs rated not less than 3A. Flexible power supply cables must be compatible with Article 400 of NEC and Table 11 and 12 of the CEC.

Handling circuit cards

CAUTION

Static electricity can damage circuit cards. Wear an antistatic wrist strap when handling circuit cards or their components.

Follow these precautions when handling circuit cards:

1. Unpack or handle cards away from electric motors, transformers, or

similar machinery.

2. Handle cards by the edges only. Do not touch the contacts or

components.

3. Set cards on a protective antistatic bag. If an antistatic bag is not

available, hold the card or set it in a card slot unseated.

4. Store cards in protective packing.

5. Do not stack cards on top of each other unless they are packaged.

6. Wear a properly connected antistatic wrist strap when you work on the

equipment.

Introduction

The PRI (Peripheral Rate Interface) Gateway is a digital trunk gateway that enables access to the Public Switched Telephone Network (PSTN) for telephones and other IP Phones or other PBXs as shown in.

28 Overview of the PRI Gateway

Figure 2 Position of the PRI Gateway in the Communication Server 1000E system

The PRI Gateway supports four E1/T1 spans that can be expanded to eight E1/T1 spans. In addition, the PRI Gateway:

• emulates and is configured as a Media Gateway 1000E

• is fully compliant with the E1/T1 alarms and Integrated Services Digital

Network (ISDN) protocols of the CE-MUX card

• uses one downloadable D-channel daughterboard to serve two E1/T1

spans

• has onboard clock reference functionality (eliminates the need for a

clock controller daughterboard), which is system-software transparent

• supports full flexible configuration so that:

— each of the E1/T1 spans in the PRI Gateway can be configured as

E1 or T1

— multicountry E1/T1 ISDN protocols can be configured for each

span; each E1/T1 span can be configured with any PRI protocol

System conﬁgurations

The CS 1000 Media Gateway 1000E (MG 1000E) uses Media Gateway Controllers (MGC) and DSP daughterboards (DSP DB) along with CE-MUX cards to support PRI digital trunks. For each MG 1000E chassis, an IPE shelf configuration supporting only one E1/T1 span for each card along with one D-channel (DCH) daughterboard (for each slot) and one clock controller daughterboard is used.

The PRI Gateway uses the MGCr with its DSP DBs along with an E1/T1 card that supports four to eight E1/T1 spans with up to four downloadable D-channel (DDCH) daughterboards. This configuration supports any PRI protocol variant in the CS 1000E system.

As shown in Figure 3 "PRI Gateway configuration" (page 29), the PRI Gateway replaces the MG 1000E as a PRI/PRI2 digital trunk gateway.

30 Overview of the PRI Gateway

CE-MUX support

The E1/T1 card supports the CE-MUX interface from the MGC for up to eight PRI spans. The new E1/T1 card added into this PRI Gateway in CS 1000 Release 5.0 emulates the CE-MUX cards (NTAK09 and NTBK50AA).

Table 4 "CE-MUX daughterboards supported by the E1/T1 card" (page

30) shows the D-channel daughterboards that are supported by the E1/T1

card and its expansion.

ATTENTION

The PRI Gateway eliminates the need for a clock controller daughterboard. The clock controller functionality is provided internally.

Shelf slot assignments

The PRI Gateway chassis has two physical backplane slots: one for the MGC with its DSP daughterboards and the other for the new E1/T1 card and its expansion daughterboards.

The E1/T1 card emulates an MG 1000E with eight CE-MUX PRI/PRI2 cards, supported in card positions 1 to 8 with DSPs using a total of 16 slot assignments.

Table 5 "Shelf slot assignments" (page 31) describes the 16 slot

assignments and their mapping.
