The remote IMACS systems must be configured with the TCP/IP CPU software option. Remote IMACS units send
management information in IP packets over the FDL to an intervening AT&T DACS II. The DACS II can be
configured to convert the IP management information from the FDL channel into a full DS0 using a link level
protocol called Bit-4 Redundant (B4R). Even though the management information is only 4 Kbps it will occupy the
full 64 Kbps DS0. The resulting 8 DS0s are then routed over T1 link(s) to the IMACS that contains the 822860.
Physically the 822860 is the same card as the 822060 SRU card. Both have ten RJ-48 interface ports, but on the
822860 the first eight are physically disabled and, effectively, replaced by eight “internal” ports used for the DS0s.
The ninth RJ-48 port is available for maintenance and the tenth RJ-48 port is used for the aggregate SLIP line to the
terminal server. Table 19 details the BnR IP concentrator card specifications.

7. PortMaster Integrated Office Router (PM-IOR)
Introduction:
The Zhone Technologies Integrated Office Router (IOR) integrates Internet/LAN connectivity within the IMACS
and StreamLine product solutions. From a single customer premises device, the IOR card, in conjunction with other
voice and data cards, will allow service providers to bundle voice, data, ISDN, and Internet services.
The IOR is a collaborative effort on the part of Lucent Technologies and Zhone Technologies. The hardware design
is built from the Lucent model OR-HS, (Office Router, High-speed), and the Zhone Technologies model 821460
dual port V.35. The model number of the IOR is 828060. The IOR is a single blade device in the form factor of the
Zhone Technologies modules provides a fully featured IP (IPX) router card that operates in both Zhone
Technologies IMACS and StreamLine chassis. The versions for the host software supporting the IOR are the
StreamLine 1.1 and IMACS 3.8/5.1.
The IOR is fully standards compliant. The card provides secure Internet access, firewall packet filtering, LAN-to-
LAN connectivity, and management of the communications network.
