MCC1 Media Gateway

Issue 6 February 2007 207

Port carrier for DEFINITY Server SI,

S8700-series Media Server, or S8500 Media Server (J58890BB)

A port carrier (J58890BB) contains the following slots:

● Port slot locations 1 to 20 for the port circuit packs.

For a DEFINITY Server SI PPN, all slots are available for optional circuit packs.

For a fiber-PNC PN, slot 1 contains a Tone-Clock or IPSI circuit pack when the port carrier

is in the B position of an EPN cabinet in a duplicated bearer configuration. Slot 2 contains

an EI or ATM Interface circuit pack for a duplicated bearer configuration. Slot 3 would also

contain an EI circuit pack for a direct-connect configuration. Otherwise, all slots are

available for optional circuit packs.

For an IP-PNC PN, slot 1 contains an IPSI circuit pack when the port carrier is in the B

position of a PN in a duplicated control network configuration. An IP Media Processor or IP

Media Resource 320 circuit pack is required in the PN, but can be inserted into any carrier

included in the PN. The other slots in a port carrier can contain optional port circuit packs.

If the MCC1 PN connects to branch location media gateways or adjuncts in the network,

supports IP endpoints, or uses IP trunks, the following circuit pack is also required:

- TN799DP control LAN (C-LAN) interface

on page 244

● A power unit service slot in which a power unit circuit pack or service circuit pack can be

installed.

● Slots at each end of the carrier for AC or DC power units.

The following figure, Figure 57:

Port carrier (J58890BB) on page 207, shows an example of a
