16 CH VoIP Media Gateway Expansion Daughter Board (16VOIPDB) —
P/N 0891023
The 16VOIPDB daughter board provides:
● 16 channels
● Connector for the 16VOIPU PCB (combination provides a maxi-
mum of 32 channels per slot)
The VOIPDB is installed on the 16VOIPU PCB with a maximum of 16
daughter boards per system, providing 512 channels (when combining
the 16VOIPU and VOIPDB). The PCB will consume 16 extension ports
and, if available, 16 trunk ports.
10/100BaseT 8-Port Switching Hub (8SHUBU) — P/N 0891021
The LAN PCB is an 8-port switching hub which complies with the ethernet
speciÞcation for both 100Base-TX and 10Base-T. This PCB is compatible
in LAN applications using 10Mbps and 100Mbps. All ports will automati-
cally identify and switch 100Base-TX, 10Base-T and Full/Half Duplex.
The 4VOIPU or 16VOIPU PCB, which is required in order for IP tele-
phones to communicate with non-VoIP Aspire phones, as well as to place
or receive outside calls, must be connected to either an external switching
hub or to the 8SHUBU PCB.
The PCB plugs into a universal slot, with a maximum of 8 PCBs per sys-
tem. No ports are consumed with the installation of this PCB. Each PCB
provides 8 RJ45 port connectors. These are used to connect to LAN terminals. Depending on the
type of LAN terminal, the PCB may not be able to detect the difference between straight cable and
cross-cable automatically. If auto-crossover is not functioning, use straight cable for that terminal
connection.
