RTM-8410 Rear Transition Module
The RTM-8410 rear transition module is housed in the device's rear panel and interfaces
with the 8410 blade in the front-panel chassis through the midplane. The number of blades
and functionality depend on the supplied system:
Mediant 3000 with 8410 blade (i.e., TP-8410):
The RTM-8410 provides and routes
DS1 (E1/T1) PSTN interfaces to the active 8410 blade (in the front panel). The RTM-
8410 also provides two Gigabit Ethernet interfaces (RJ-45 ports) for connecting the
device to the LAN (IP network), using Cat 5 LAN cables. The number of RTM-8410
RTMs housed in the chassis depends on the number of supported E1/T1 interfaces:
•
42-84 E1/T1 spans:
Two RTM-8410s for Simplex and HA configurations. The
PSTN interfaces are provided by two SCSI connectors per RTM-8410 (100-Pin
female SCSI connector and 68-Pin female SCSI connector), supporting up to 42
DS1 (E1/T1) trunks per RTM-8410 (therefore, up to 84 DS1 if two RTM-8410s are
used).
•
16 E1/T1 spans:
One RTM-8410, providing a single 100-pin female SCSI
connector for the trunks.
IPmedia 3000 with 8410 (i.e., IPM-8410):
The device houses only one RTM-8410.
The RTM-8410 provides two Gigabit Ethernet (RJ-45) ports for interfacing with the IP
network for voice and video IP media processing (e.g., video conferencing).
Notes:
•
For IPmedia 3000, the RTM-8410 providing two SCSI connectors is
implemented. However, only the Gigabit Ethernet ports are used.
•
For blade slot assignment in the chassis, refer to ''Card Cage and Slot
Assignment'' on page
