BG-30E Overview The BG-30E shelf is housed in a 240 mm deep, 465 mm wide, and 88 mm high equipment cage with all interfaces accessible from the front. The shelf consists of three expansion cards, redundant power feed modules, and an extractable fan module. All cards in the BG-30E are connected using a backplane that supports one traffic connector for the connection between the BG-30E and the BG-30B or BG-64.

NOTE: the BG-30E can be used to expand traffic for the BG-30B and BG-64 shelves. All information described for the BG-30E is applicable for both shelves.

1 This module/card can provide only balanced E1 interfaces directly. For unbalanced E1 interfaces, an external DDF with balanced-to-unbalanced conversion should be used.

A BG-30E shelf is an extension or slave unit of the BG-30B or BG-64 and should always be connected to one of these shelves. The fan unit, used to cool the system, is extractable and located on the right side of the shelf. The fan control system is on the MCP30 or MCP64 in accordance with the type of shelf it is being installed on.

Figure -2: BG-30E front view

The BG-30E houses three traffic expansion slots supporting different types of PDH, SDH, data, and PCM interface expansion cards.

Either 220 VAC or -48 VDC power feeds can be selected. BG-30E has one slot that is used for configuring the power input module. Two types can be configured: INF_30E and AC_CONV-30E:

INF_30E, used for -48 VDC power feed, provides two D-type connectors for external power line connection, and supports dual power feed.

AC_CONV-30E is used for 220 VAC power feed to implement AC/DC conversion. It supports external power line connection through a special power connector.

NOTE: Adding a BG-30E expansion unit to a working BG-30B in the field is a non-traffic-affecting operation.

BG-30E Expansion Traffic Cards The BG-30E has three expansion card slots, which can be configured with expansion cards such as PE1_63, P345_3E, MPS_2G_8F, SM_10E, S1_4, S4_1, TP21_2, and TPS1_1 cards. All expansion cards are accessible from the front and provide cabling directly through the front panels. These extension cards support live insertion for fast maintenance and recovery.

The following table lists the modules that can be configured in each slot of the BG-30E.
