This section describes the new J-series Services Routers features, available with the JUNOS 8.3R4 release. For more information, see the following manuals:
For more information about the JUNOS Internet software that runs on Services Routers, see the manuals listed in Table 6.
New high-density Gigabit Ethernet uPIMs—Three new universal Physical Interface Modules (uPIMs) provide increased port density for Gigabit Ethernet connections. The uPIMs can be installed in either high-speed or regular slots on J4350 and J6350 Services Routers running JUNOS 8.3 or later. The new uPIMs are:

Caution: You can install a maximum of three 8-port Gigabit Ethernet uPIMs in a single J4350 or J6350 chassis. If you install the maximum of three 8-port Gigabit Ethernet uPIMs, only one of the remaining slots can be occupied, and it cannot contain an ePIM, uPIM, or Avaya VoIP module. |
ISDN PRI can operate in a Services Router chassis with ISDN BRI PIMs and supports ATT5ESS, ETSI (NET5), National ISDN (NI2), DMS100, and NTT switch types. The following ISDN features are supported:
A new bchannel-allocation option enables you to allocate a free B-channel for dial-out calls. This setting directs the router to select the first free bchannel with highest number (default) or lowest when dialing out.
To configure PAP support on the physical interface, include the pap statement with options at the [edit interfaces interface-name ppp-options] hierarchy level. To configure PAP support on the logical interface, include the pap statement with options at the [edit interfaces interface-name unit logical-unit-number ppp-options] hierarchy level. To view information about the PAP states, issue the show ppp summary and show ppp interfaces operational mode commands.

Caution: Because all files saved to DRAM are deleted when the system reboots, be sure to back up these files to ensure that they are not lost. |
With the earlier minimum transmit rate you could only assign 1/1000th part of the interface speed. Therefore, if the speed of the interface was 1000 Mbps, the minimum transmit rate would be 1000 Mbps x 1/1000=1 Mbps. Now with the minimum transmit rate of 1/10000 for the same interface, you can set the transmit rate of a queue to be 1000 Mbps x 1/10000 = 100 Kbps.
